wxing1292andGitHub e0d377d8ec Attempt to unify queue state (#4190)
* Mostly deprecate queue ack level in favor of queue state
* Additional compatibility logic for forward / backward compatibility
* Use queue state for replication acks
* Allow replication streams between clusters with different shard count
