introduce helper functions that can be used for garbage collecting old cdc streams for tablets-based keyspaces. add a background fiber to the topology coordinator that runs periodically and checks for old CDC streams for tablets keyspaces that can be garbage collected. the garbage collection works by finding the newest cdc timestamp that has been closed for more than the configured cdc TTL, and removing all information from the cdc internal tables about cdc timestamps and streams up to this timestamp. in general it should be safe to remove information about these streams because they are closed for more than TTL, therefore all rows that were written to these streams with the configured TTL should be dead. the exception is if the TTL is altered to a smaller value, and then we may remove information about streams that still have live rows that were written with the longer ttl.

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.
