Exposing monitoring metrics using JMX would allow users of the connector to measure the progress of their data streams.

Add an MBean to expose the following metrics for monitoring for the Source Connector:

• Current source clusterTime (poll this directly from server, not from the last event)
• clusterTime of the last processed changeEvent
• Difference between the previous two: The lag between cluster and Source Connector

Add an MBean to expose the following metrics to the Sink Connector:

• clusterTime of the last processed change Event
• (if possible) the delta between the last processed clusterTime and the newest event in the topic: The lag of the Sink Connector
