Alternative MR replication method

This introduces a new set of replication rules for topics:
REPLICATION_EDGE_TO_FQDN
REPLICATION_FQDN_TO_EDGE
REPLICATION_EDFE_TO_FQDN_TO_GLOBAL
REPLICTION_GLOBAL_TO_FQDN_TO_EDGE

This will allow for some apps to design their own message replication
path for resiliency because it will use the FQDN of the cluster
instead of the using the CNAME.

Also contains:
- introduce (optional) replicationGroup field to mr_cluster
- some cleanup of unused code.
