 Description   
Original Downstream Change Summary

This change adds a new optional field, "remoteOpWaitMillis" to the profiler / slow query log lines. It tells you how much time the node spent waiting for results from other nodes. By comparing this with the total "durationMillis" you can figure out whether the merger or a shard is to blame for a slow query.

This change basically expands 'remoteOpWaitMillis' to any command that contacts shards.

Description of Linked Ticket

This ticket is the find() counterpart of SERVER-31368 which addresses aggregation.

Triaging to backlog. We'll move to "Ready for Work" closer to the 6.3 release.
