Add metrics to log info about pushing snapshots to server

[mwales]

What is the feature you'd like to have? Better metrics about how long it takes to push snapshot to our enterprise server. Is it slow because the snapshot is huge, network slow, etc. Work network can sometimes be intermittently slow too, would help troubleshooting efforts.

Is your feature request related to a problem? Sometimes syncing takes several minutes, sometimes very quick. There are already lots of logs about how long different analysis functions take.

Might make it a log debug but that's easy enough for folks to turn on in specific situations.
