test: Turn off tablets feature by default

Next patches will make per-keyspace initial_tables option really
optional and turn tablets ON when the feature is ON. This will break all
other tests' assumptions, that they are testing vnodes replication. So
turn the feature off by default, tests that do need tables will need to
explicitly enable this feature on their own
