Description

The stop/start replication functionality is confusing. More times then not a user really only wants to stop/start replication on a peer by peer basis. Enable/disable peer handles this need.

Removing ReplicationState and the admin commands associated with it will simplify the code without losing any major functionality.

This JIRA was created based on a discussion in HBASE-8844.
