Merged patch series from Piotr Sarna:
This series adds HTTPS support for Alternator.
The series comes with --https option added to alternator-test, which makes
the test harness run all the tests with HTTPS instead of HTTP. All the tests
pass, albeit with security warnings that a self-signed x509 certificate was
used and it should not be trusted.
Fixes#5042

Patches:
docs: update alternator entry on HTTPS
alternator-test: suppress the "Unverified HTTPS request" warning
alternator-test: add HTTPS info to README.md
alternator-test: add HTTPS to test_describe_endpoints

alternator: add HTTPS support
config: add alternator HTTPS port
The BEGINS_WITH condition in conditional updates (via Expected) requires
that the given operand be either a string or a binary. Any other operand
should result in a validation exception - not a failed condition as we
generate now.
This patch fixes the test for this case so it will succeed against
Amazon DynamoDB (before this patch it fails - this failure was masked by
a typo before commit 332ffa77ea). The patch
then fixes our code to handle this case correctly.
Note that BEGINS_WITH handling of wrong types is now asymmetrical: A bad
type in the operand is now handled differently from a bad type in the
attribute's value. We add another check to the test to verify that this
is the case.

Running with --https and a self-signed certificate results in a flood
of expected warnings, that the connection is not to be trusted.
These warnings are silenced, as users runing a local test with --https
usually use self-signed certificates.
The test_describe_endpoints test spawns another client connection
to the cluster, so it needs to be HTTPS-aware in order to work properly
with --https parameter.
Running with --https parameter will result in sending the requests
via HTTPS instead of HTTP. By default, port 8043 is used for a local
cluster. Before running pytest --https, make sure that Scylla
was properly configured to initialize a HTTPS alternator server
by providing the alternator_tls_port parameter.
The HTTPS-based connection runs with verification disabled,
otherwise it would not work with self-signed certificates,
which are useful for tests.
The test test_update_expression_function_nesting() fails because DynamoDB
don't allow an expression like list_append(list_append(:val1, :val2), :val3)
but Alternator doesn't check for this (and supports this expression).
The "xfail" message was outdated, suggesting that the test fails because
the "SET" expression isn't supported - but it is. So replace the message
by a more accurate one.

This patch adds tests for all the missing comparion operators in the
Expected parameter (the old-style parameter for conditional operations).
All these new tests are now xfailing on Alternator (and succeeding on
DynamoDB), because these operators are not yet implemented in Alternator
(we only implemented EQ and BEGINS_WITH, so far - the rest are easy but
need to be implemented).
The test_expected.py is now hopefully comprehensive, covering the entire
feature set of the "Expected" parameter and all its various cases and
subcases.

Our implementation of the "EQ" operator in Expected (conditional
operation) just compares the JSON represntation of the values.
This is almost always correct, but unfortunately incorrect for
sets - where we can have two equal sets despite having a
different order.
This patch just adds an (xfailing) test for this bug.
The bug itself can be fixed in the future in one of several ways
including changing the implementation of EQ, or changing the
serialization of sets so they'll always be sorted in the same
way.

In this patch we implement the Expected parameter for the UpdateItem,
PutItem and DeleteItem operations. This parameter allows a conditional
update - i.e., do an update only if the existing value of the item
matches some condition.
This is the older form of conditional updates, but is still used by many
applications, including Amazon's Tic-Tac-Toe demo.
As usual, we do not yet provide isolation guarantees for read-modify-write
operations - the item is simply read before the modification, and there is
no protection against concurrent operation. This will of course need to be
addressed in the future.
The Expected parameter has a relatively large number of variations, and most
of them are supported by this code, except that currenly only two comparison
operators are supported (EQ and BEGINS_WITH) out of the 13 listed in the
documentation. The rest will be implemented later.
This patch also includes comprehensive tests for the Expected feature.
These tests are almost exhaustive, except for one missing part (labled FIXME) -
among the 13 comparison operations, the tests only check the EQ and BEGINS_WITH
operators. We'll later need to add checks to the rest of them as well.
As usual, all the tests pass on Amazon DynamoDB, and after this patch all
of them succeed on Alternator too.

Even when running against a local Alternator, Boto3 wants to know the
region name, and AWS credentials, even though they aren't actually needed.
For a local run, we can supply garbage values for these settings, to

Running against "--aws" will, of course, still require the user to

Unfortunately the previous 100s limit proved to be not enough
for creating tables with both local and global indexes attached
to them. Empirically 200s was chosen as a safe default,
as the longest test oscillated around 100s with the deviation of 10s.
We currently reserve the column name "attrs" for a map of attributes,
so the user is not allowed to use this name as a name of a key.
We plan to lift this reservation in a future patch, but until we do,
let's at least choose a more obscure name to forbid - in this patch ":attrs".
It is even less likely that a user will want to use this specific name
as a column name.

Currently, we reserve the name ATTRS_COLUMN_NAME ("attrs") - the user
cannot use it as a key column name (key of the base table or GSI or LSI)
because we use this name for the attribute map we add to the schema.
Currently, if the user does attempt to create such a key column, the
result is undefined (sometimes corrupt sstables, sometimes outright crashes).
This patches fixes it to become a clean error, saying that this column name is
currently reserved.
The test test_create_table_special_column_name now cleanly fails, instead
of crashing Scylla, so it is converted from "skip" to "xfail".
Eventually we need to solve this issue completely (e.g., in rare cases
rename columns to allow us to reserve a name like ATTRS_COLUMN_NAME,
or alternatively, instead of using a fixed name ATTRS_COLUMN_NAME pick a
different one different from the key column names). But until we do,
better fail with a clear error instead of a crash.

The file initially consists of a very simple case that succeeds
with `--aws` and expectedly fails without it, because the expression
is not implemented yet.
The test_gsi_3, involving creating a GSI with two key columns which weren't
previously a base key, now passes, so drop the "xfail" marker.
We still have problems with such materialized views, but not in the simple
scenario tested by test_gsi_3.
Later we should create a new test for the scenario which still fails, if
any.

It is important that BillingMode should default to PROVISIONED, as it

When querying on a missing index, DynamoDB returns different errors in
case the entire table is missing (ResourceNotFoundException) or the table
exists and just the index is missing (ValidationException). We didn't
make this distinction, and always returned ValidationException, but this
confuses clients that expect ResourceNotFoundException - e.g., Amazon's
Tic-Tac-Toe demo.
This patch adds a test for the first case (the completely missing table) -
we already had a test for the second case - and returns the correct
error codes. As usual the test passes against DynamoDB as well as Alternator,
ensure they behave the same.

Alternator puts in the Scylla table a column called "attrs" for all the
non-key attributes. If the user happens to choose the same name, "attrs",
for one of the key columns, the result of writing two different columns
with the same name is a mess and corrupt sstables.
This test reproduces this bug (and works against DynamoDB of course).
Because the test doesn't cleanly fail, but rather leaves Scylla in a bad
state from which it can't fully recover, the test is marked as "skip"
until we fix this bug.

The test test_update_expression_cannot_modify_key() verifies that an
update expression cannot modify one of the key columns. The existing
test only tried the SET and REMOVE actions - this patch makes the
test more complete by also testing the ADD and DELETE actions.
This patch also makes the expected exception more picky - we now
expect that the exception message contains the word "key" (as it,
indeed, does on both DynamoDB and Alternator). If we get any other
exception, there may be a problem.
The test passed before this patch, and passes now as well - it's just
stricter now.

With more GSI features implemented, tests with XPASS status are promoted
to being enabled.
One test case (test_gsi_describe) is partially done as DescribeTable
now contains index names, but we could try providing more attributes
(e.g. IndexSizeBytes and ItemCount from the test case), so the test
is left in the XFAIL state.
We allow BillingMode to be set to either PAY_PER_REQUEST (the default)
or PROVISIONED, although neither mode is fully implemented: In the former
case the payment isn't accounted, and in the latter case the throughput
limits are not enforced.
But other settings for BillingMode are now refused, and we add a new test
to verify that.

The alternator tests want to exercise many of the DynamoDB API features,
so they need a recent enough version of the client libraries, boto3
and botocore. In particular, only in botocore 1.12.54, released a year
ago, was support for BillingMode added - and we rely on this to create
pay-per-request tables for our tests.
Instead of letting the user run with an old version of this library and
get dozens of mysterious errors, in this patch we add a test to conftest.py
which cleanly aborts the test if the libraries aren't new enough, and
recommends a "pip" command to upgrade these libraries.

The DescribeTable operation was currently implemented to return the
minimal information that libraries and applications usually need from
it, namely verifying that some table exists. However, this operation
is actually supposed to return a lot more information fields (e.g.,
the size of the table, its creation date, and more) which we currently
don't return.
This patch adds a new test file, test_describe_table.py, testing all
these additional attributes that DescribeTable is supposed to return.
Several of the tests are marked xfail (expected to fail) because we
did not implement these attributes yet.
The test is exhaustive except for attributes that have to do with four
major features which will be tested together with these features: GSI,
LSI, streams (CDC), and backup/restore.

This patch adds partial support for GSI (Global Secondary Index) in
Alternator, implemented using a materialized view in Scylla.
This initial version only supports the specific cases of the index indexing
a column which was already part of the base table's key - e.g., indexing
what used to be a sort key (clustering key) in the base table. Indexing
of non-key attributes (which today live in a map) is not yet supported in
this version.
Creation of a table with GSIs is supported, and so is deleting the table.
UpdateTable which adds a GSI to an existing table is not yet supported.
Query and Scan operations on the index are supported.
DescribeTable does not yet list the GSIs as it should.
Seven previously-failing tests now pass, so their "xfail" tag is removed.

test_gsi_key_not_in_index(), where the index's key includes just one of
the base table's key columns, but not a second one. In this case, the

to the view (as a clustering key), even though it isn't considered a key

Although we do not support GSI yet, until now we silently ignored
CreateTable's GSI parameter, and the user wouldn't know the table

In this patch, GSI is still unsupported, but now CreateTable will

We need to change some of the tests which test the error path, and

The test case for adding two sets with common values is added.
This case is a stub, because boto3 transforms the result into a Python
set, which removes duplicates on its own. A proper TODO is left
in order to migrate this case to a lower-level API and check
the returned JSON directly for lack of duplicates.
