Replication status tool

In the event of manual failover, there should be a tool that cluster administrators can run while the master cluster is stopped, that will indicate whether data from the master cluster has been successfully replicated to the slave cluster.

The scope of this JIRA is purely for a manual failover and does not cover a disaster recovery scenario.
