Description

This is for allowing specify cluster key without zookeeper in replication peer config.

For now, we will set a watcher on zookeeper for fetching the region server list for the remote cluster, this means we must know the zookeeper address of the remote cluster. This should be fixed as we do not want to leak the zookeeper outside the cluster itself.
