In commit a3ec6c7d1d we supposedly
implemented the feature of telling TTL experation events from regular
user-sent deletions. However, that implementation did not actually work
at all... It had two bugs:
1. It created an null rjson::value() instead of an empty dictionary
rjson::empty_object(), so GetRecords failed every time such a
TTL expiration event was generated.
2. In the output, it used lowercase field names "type" and "principalId"
instead of the uppercase "Type" and "PrincipalId". This is not the
correct capitalization, and when boto3 recieves such incorrect
fields it silently deletes them and never passes them to the user's
get_records() call.
This patch fixes those two bugs, and importantly - enables a test for
this feature. We did already have such a test but it was marked as
"veryslow" so doesn't run in CI and apparently not even run once to
check the new feature. This test is not actually very long on Alternator
when the TTL period is set very low (as we do in our tests), so I replaced
the "veryslow" marker by "waits_for_expiration". The latter marker means
that the test is still very slow - as much as half an hour - on DynamoDB -
but runs quickly on Scylla in our test setup, and enabled in CI by
default.
The enabled test failed badly before this patch (a server error during
GetRecords), and passes with this patch.
Also, the aforementioned commit forgot to remove the paragraph in
Alternator's compatibility.md that claims we don't have that feature yet.
So we do it now.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
