 Description   

Currently, the initial sync provides some initial sync feedback on the current collection being synchronized, but there isn't any feedback on how far along the entire initial sync is. Ideally, an overall percentage or an estimate of the time for the sync to complete would be a useful addition to the logs.

Edit: The current plan is to provide per collection progress as they are copied by providing counts for the number of documents inserts/total-at-start periodically. Also, it may be possible to provide this information in heartbeat messages so that rs.status() includes more information which can be seen in other tools.

We have a naive progress meter for initial sync progress now.
