When running compaction task test on the same scylla instantion
other tests are run, some compaction tasks from other test cases may
be left in task manager. If they stay in memory long enough, they may
get unregistered during the compaction task test and cause bad_request
status.
Drain old compaction tasks before and after each test.
Fixes: #14584.
Closes#14585
This reverts commit 2a58b4a39a, reversing
changes made to dd63169077.
After patch 87c8d63b7a,
table_resharding_compaction_task_impl::run() performs the forbidden
action of copying a lw_shared_ptr (_owned_ranges_ptr) on a remote shard,
which is a data race that can cause a use-after-free, typically manifesting
as allocator corruption.
Note: before the bad patch, this was avoided by copying the _contents_ of the
lw_shared_ptr into a new, local lw_shared_ptr.

In test_compaction_task.py tests concerning the same type of compaction
are squashed together so that they are run synchronously and there is
no data race when the tests are run in parallel.
