Alternator Streams' "ListStreams" does paging by returning a "cookie" LastEvaluatedStreamArn from one request, that the user passes to the next request as ExclusiveStartStreamArn. In the past, Alternator's stream ARNs were UUIDs, but we recently changed them to match DynamoDB's ARN format which the KCL library requires. However, we didn't change ListStream's cookie format, and it remained UUIDs. This, however, goes against the documentation of DynamoDB, which states that LastEvaluatedStreamArn should be "the stream ARN of the item where the operation stopped". It shouldn't be some weird opaque cookie. So in this patch we add a test that confirms that indeed, in DynamoDB the LastEvaluatedStreamARN is really the last returned ARN and not an opaque cookie. The new test passes on DynamoDB, and fails on Alternator before the simple fix that this patch then does. Fixes SCYLLADB-539.

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.
