Increase pool size changes were recently reverted because of the flakiness for the test_gossip_boot test. Test started
to fail on adding the node to the cluster without any issues in the Scylla log file. In test logs it looked like the
installation process for the new node just hanged. After investigating the problem, I've found out that the issue is that
test.py was draining the io_executor pool for cleaning the directory during install that was set to eight workers. So
to fix the issue, io_executor pool should be increased to more or less the same ratio as it was: doubled cluster pool size.
Closesscylladb/scylladb#20276
This includes
- marking the suite as Topology
- import needed fixtures and options from topology conftest
- configuring the zero initial cluster size and anonymous auth
- marking all test cases as skipped, as they no longer work after above

instead of using a single run to perform the test, restructure
it into a pytest based test suite with a single test case.
this should allow us to add more tests exercising the object-storage
and cached/tierd storage in future.
* add fixtures so they can be reused by tests
* use tmpdir fixture for managing the tmpdir, see
https://docs.pytest.org/en/6.2.x/tmpdir.html#the-tmpdir-fixture
* perform part of the teardown in the "test_tempdir()" fixture
* change the type of test from "Run" to "Python"
* rename "run" to "test_basic.py"
* optionally start the minio server if the settings are not
found in command line or env variables, so that the tests are
self-contained without the fixture setup by test.py.
* instead of sys.exit(), use assert statement, as this is
what pytest uses.

The test does
- starts scylla (over stable directory
- creates S3-backed keyspace (minio is up and running by test.py
already)
- creates table in that keyspace and populates it with several rows
- flushes the keyspace to make sstables hit the storage
- checks that the ownership table is populated properly
- restarts scylla
- makes sure old entries exist
