DNAC-Cyclops

Description (partial)

Symptom:
After a DR failover, the subsequent DR rejoin failed with dr-mongodb-replicator stuck in CrashLoopBackOff state, with logging error:

"Oplog Tailer initialize failed: ... node is recovering"

Conditions:
This happens when one or both of the MongoDB standby nodes are in "RECOVERING" state on the DR active cluster side. 

Since the new DR active cluster was the original DR passive cluster before the DR failover, the MongoDB standby nodes stuck in "RECOVERING" state may have occurred before the DR failover operation.
