This task is to make changes necessary to mongodb servers to support restoring shards or whole sharded clusters from backups when the config servers use the CSRS (SERVER-1448) config server protocols.

The procedures to support are:

• Restoring an entire sharded cluster from a backup in place (same host names and ports)
• Restoring an entire, new sharded cluster from a backup of a different sharded cluster (different hosts/ports).
• Restoring a single shard of a sharded cluster from a backup of that shard from that cluster.
