Finishing the deprecation of the skip_mode function in favor of
pytest.mark.skip_mode. This PR is only cleaning and migrating leftover tests
that are still used and old way of skip_mode.
Closesscylladb/scylladb#28299
Function skip_mode works only on function and only in cluster test. This if OK
when we need to skip one test, but it's not possible to use it with pytestmark
to automatically mark all tests in the file. The goal of this PR is to migrate
skip_mode to be dynamic pytest.mark that can be used as ordinary mark.

Enable all counters-related tests that were disabled for tablets because
counters was not supported with tablets until now.
Some tests were parametrized to run with both vnodes and tablets, and
the tablets case was skipped, in order to not lose coverage. We change
them to run with the default configuration since now counters is
supported with both vnodes and tablets, and the implementation is the
same, so there is no benefit in running them with both configurations.
Topology version is now bumped when a node finishes bootstrapping.
As a result, fence_version == version - 1, and decrementing version
in the test no longer triggers a stale topology exception.
Fix: run cleanup_all to invoke the global barrier, which synchronizes
fence_version := version on all nodes.
This test verifies that the fencing token is checked on replicas
after the local Paxos state is updated. This ensures that if we failed
to drain an LWT request during topology changes the replicas
where paxos verbs got stuck won't contributed to the target CLs.
We adjust all of the simple cases of cluster tests so they work
with `rf_rack_valid_keyspaces: true`. It boils down to assigning
nodes to multiple racks. For most of the changes, we do that by:
* Using `pytest.mark.prepare_3_racks_cluster` instead of
`pytest.mark.prepare_3_nodes_cluster`.
* Using an additional argument -- `auto_rack_dc` -- when calling
`ManagerClient::servers_add()`.
In some cases, we need to assign the racks manually, which may be
less obvious, but in every such situation, the tests didn't rely
on that assignment, so that doesn't affect them or what they verify.
The new option deprecates the existing `enable_tablets` option.
It will be extended in the next patch with a 3rd value: "enforced"
while will enable tablets by default for new keyspace but
without the posibility to opt out using the `tablets = {'enabled':
false}` keyspace schema option.
