Tests MM2 replication and failover/failback logic.

MM2 is configured with active/active replication between two Kafka clusters. Tests validate that
records sent to either cluster arrive at the other cluster. Then, a consumer group is migrated from
one cluster to the other and back. Tests validate that consumer offsets are translated and replicated
between clusters during this failover and failback.
