HDDS-7058. EC: ReplicationManager - Implement ratis container replication check handler

[sodonnel]

What changes were proposed in this pull request?

Create a handler for the new replication manager to process Ratis container and detect under / over / mis-replication issues.

The logic is largely unchanged from the LegacyReplication manager - simply packaged into the new "handler" structure.

At the moment, this code will not be executed by the new replication manager, as all non-EC container will be directed to the Legacy Replication Manager for processing.

This Jira is part of the work to remove the Legacy Replication Manager.
