Michał Jadwiszczak da82c5f0b0 cql3:statements: run service level statements on shard0 with raft guard
To migrate service levels to be raft managed, obtain `group0_guard` to
be able to pass it to service_level_controller's methods.

Using this mechanism also automatically provides retries in case of
concurrent group0 operation.
