Display the feature compatibility version (FCV) in Cloud Manager/Ops Manager UI
The FCV could be different than the MongoDB version. Also, sometime the FCV on different shards/CSRS in a sharded cluster might be different (e.g. FCV is upgraded on the shards, but for some reason FCV is not upgraded on the CSRS), and this could cause issues.
It would be nice if FCV is displayed next to the MongoDB version information. So that we can spot out the discrepancy quickly.
