Before work on tablets was completed, it was noticed that — due to some missing pieces of implementation — Scylla doesn't properly close sstables for migrated-away tablets. Because of this, disk space wasn't being reclaimed properly. Since the missing pieces of implementation were added, the problem should be gone now. This patch adds a test which was used to reproduce the problem earlier. It's expected to pass now, validating that the issue was fixed. Should be backported to branch-6.0, because the tested problem was also affecting that branch. Fixes #16946 Closes scylladb/scylladb#18906 * github.com:scylladb/scylladb: test_tablets: add test_tablet_storage_freeing test: pylib: add get_sstables_disk_usage()

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.
