Show time it took to complete a snapshot
In order to better troubleshoot snapshot performance issues, or maintain an understanding of how snapshots are performing and whether one is approaching a threshold where they wont be able to keep up, its a good idea to expose how long a snapshot took in the View All Snapshots page. This would also aid in quickly identifying which snapshots are full vs incremental.
In addition, it could be useful that OpsManager backup process periodically captures (configurable?) throughput metrics on each replica set member of sharded cluster being backed up, so that chart/report can be done to shed light on backup agent/storage efficiency drops (contentions, duration biases in specific time ranges...)
