Instead of blindly returning "localhost:8000" in response to
DescribeEndpoints and for sure causing us problems in the future,
the right thing to do is to return the same domain name which the
user originally used to get to us, be it "localhost:8000" or
"some.domain.name:1234". But how can we know what this domain name
was? Easy - this is why HTTP 1.1 added a mandatory "Host:" header,
and the DynamoDB driver I tested (boto3) adds it as expected,
indeed with the expected value of "localhost:8000" on my local setup.

DescribeEndpoints is not a very important API (and by default, clients
don't use it) but I wanted to understand how DynamoDB responds to it,
and what better way than to write a test :-)
And then, if we already have a test, let's implement this request in
Scylla as well. This is a silly implementation, which always returns
"localhost:8000". In the future, this will need to be configurable -
we're not supposed here to return *this* server's IP address, but rather
a domain name which can be used to get to all servers.

Add an initial UpdateItem implementation. As PutItem and GetItem we
are still limited to string attributes. This initial implementation
of UpdateItem implements only the "PUT" action (not "DELETE" and
certainly not "ADD") and not any of the more advanced options.

Add an initial implementation of Delete table, enough for making the
pytest --local test_table.py::test_create_and_delete_table
Pass.

This initial implementation is enough to pass a test of getting a
failure for a non-existant table -
test_table.py::test_describe_table_non_existent_table
and to recognize an existing table. But it's still missing a lot
of fields for an existing table (among others, the schema).

The interface works on port 8000 by default and provides
the most basic alternator operations - it's an incomplete
set without validation, meant to allow testing as early as possible.
