The cleanup compaction wants to keep local tokens on-board and gets
them from storage_service.get_local_ranges().
This method is the wrapper around database.get_keyspace_local_ranges()
created in previous patch, the live database reference is already
available on the descriptor's options, so we can short-cut the call.
This allows removing the last explicit call for global storage_service
instance from compaction code.
