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. Closes scylladb/scylladb#27853 [avi: apply to test/cluster/test_tablets.py::test_table_creation_wakes_up_balancer]
