Add more racks to dc2 to verify that the default replication factor
covers all available racks (rather than e.g. limited to 3).
With tablets and rf_rack_valid_keyspaces, verify also the automatically
selected rack list.
Restrict the extension to non-debug build modes to prevent running out
of memory with --repeat=100.

The patch marks force-gossip-topology-changes as deprecated and removes
tests that use it. There is one test (test_different_group0_ids) which
is marked as xfail instead since it looks like gossiper mode was used
there as a way to easily achieve a certain state, so more investigation
is needed if the tests can be fixed to use raft mode instead.

Add test cases for create keyspace default replication factor.
It is expected that the default replication factor is equal to the
number of racks containing at least some non-zero-token nodes
in the test suite.
