Merged pull request https://github.com/scylladb/scylla/pull/5381 by
Peng Jian, fixing multiple small issues with Redis:
* Rename the options related to Redis API, and describe them clearly.
* Rename redis_transport_port to redis_port
* Rename redis_transport_port_ssl to redis_ssl_port
* Rename redis_default_database_count to redis_database_count
* Remove unnecessary option enable_redis_protocol
* Modify the default value of opition redis_read_consistency_level and redis_write_consistency_level to LOCAL_QUORUM
* Fix the DEL command: support to delete mutilple keys in one command.
* Fix the GET command: return the empty string when the required key is not exists.
* Fix the redis-test/test_del_non_existent_key: mark xfail.
Rename option redis_transport_port to redis_port, which the redis transport listens on for clients.
Rename option redis_transport_port_ssl to redis_ssl_port, which the redis TLS transport listens on for clients.
Rename option redis_database_count. Set the redis dabase count.
Rename option redis_keyspace_opitons to redis_keyspace_replication_strategy_options. Set the replication strategy for redis keyspace.
Remove option enable_redis_protocol, which is unnecessary.
Fixes: #5335

This patch series adds only UDF support, UDA will be in the next patch series.
With this all CQL types are mapped to Lua. Right now we setup a new
lua state and copy the values for each argument and return. This will
be optimized once profiled.
We require --experimental to enable UDF in case there is some change
to the table format.

Merged patch series from Botond Dénes:
This series extends the existing docs/debugging.md with a detailed guide
on how to debug Scylla coredumps. The intended target audience is
developers who are debugging their first core, hence the level of
details (hopefully enough). That said this should be just as useful for
seasoned debuggers just quickly looking up some snippet they can't
remember exactly. A Throubleshooting chapter is also added in this
series for commonly-met problems.
I decided to create this guide after myself having struggled for more
than a day on just opening(!) a coredump that was produced on Ubuntu.
As my main source, I used the How-to-debug-a-coredump page from the
internal wiki which contains many useful information on debugging
coredumps, however I found it to be missing some crucial information, as
well being very terse, thus being primarily useful for experienced
debuggers who can fill in the blanks. The reason I'm not extending said
wiki page is that I think this information should not be hidden in some
internal wiki page. Also, docs/debugging.md now seems to be a much
better base for such a document. This document was started as a
comprehensive debugging manual for beginners (but not just).
You will notice that the information on how to debug cores from
CentOS/Redhat are quite sparse. This is because I have no experience
with such cores, so for now the respective chapters are just stubs. I
intend to complete them in the future after having gained the necessary
experience and knowledge, however those being in possession of said
knowledge are more then welcome to send a patch. :)

To the 'Debuggin Scylla with GDB` chapter. The '### Debugging
relocatable binaries built with the toolchain' subchapter is demoted to
be just a section in this new subchapter. It is also renamed to
'Relocatable binaries'.
This subchapter intends to be a complete guide on how to debug coredumps
from how to obtain the correct version of all the binaries all the way
to how to correctly open the core with GDB.

Merged patch set from Piotr Sarna:
Refs #5046
This commit adds handling "Authorization:" header in incoming requests.
The signature sent in the authorization is recomputed server-side
and compared with what the client sent. In case of a mismatch,
UnrecognizedClientException is returned.
The signature computation is based on boto3 Python implementation
and uses gnutls to compute HMAC hashes.
This series is rebased on a previous HTTPS series in order to ease
merging these two. As such, it depends on the HTTPS series being
merged first.
Tests: alternator(local, remote)
The series also comes with a simple authorization test and a docs update.

The example Python code had wrong indentation, and wouldn't actually
work if naively copy-pasted. Noticed by Noam Hasson.

A documentation file that is intended to be a place for anything
debugging related: getting started tutorial, tips and tricks and
advanced guides.
For now it contains a short introductions, some selected links to
more in-depth documentation and some trips and tricks that I could think
off the top of my head.
One of those tricks describes how to load cores obtained from
relocatable packages inside the `dbuild` container. I originally
intended to add that to `tools/toolchain/README.md` but was convinced
that `docs/debugging.md` would be a better place for this.

This patch adds a getting started document for alternator,
it explains how to start up a cluster that has an alternator
API port open and how to test that it works using either an
application or some simple and minimal python scripts.
The goal of the document is to get a user to have an up and
running docker based cluster with alternator support in the
shortest time possible.
As part of trying to make alternator more accessible
to users, we expect more documents to be created so
it seems like a good idea to give all of the alternator
docs their own directory.
This adds a "alternator-address" and "alternator-port" configuration
options to the Docker image, so people can enable Alternator with
"docker run" with:
docker run --name some-scylla -d <image> --alternator-port=8080

This adds a new document, docs/alternator.md, about Alternator.
The scope of this document should be expanded in the future. We begin
here by introducing Alternator and its current compatibility level with
Amazon DynamoDB, but it should later grow to explain the design of Alternator
and how it maps the DynamoDB data model onto Scylla's.
Whether this document should remain a short high-level overview, or a long
and detailed design document, remains an open question.

Recently we started to use more the concept of metric labels - several
metrics which share the same name, but differ in the value of some label
such a "group" (for different scheduling groups).
This patch documents this feature in docs/metrics.md, gives the example of
scheduling groups, and explains a couple more relevant Promethueus syntax
tricks.

Prometheus needs to remember which "instance" (node) each measurement
came from. But it doesn't actually need Scylla to tell it the instance
name - it knows which node it got each measurement from.
After Seastar commit 79281ef287
which fixed Seastar issue https://github.com/scylladb/seastar/issues/477,
the "instance" label on measurements no longer comes from Scylla but rather
is added by Prometheus. This patch corrects the documentation to explain the
current situation, instead of incorrectly saying that Scylla adds the
"instance" label itself.
