Since we have temporarily disabled the resync command while reworking code and bringing the DataReplicator into the mix, we need to re-enable support for it and its tests.
These are the expected behaviors:
- Each resync command will cancel any existing data replication and start a new resync (an initial sync)
- A resync will block waiting for the initial sync to complete
- During an initial sync the ReplSetSyncFrom command will set the sync source and issue a resync command internally – having the effect that the initial syncs first attempt uses the supplied host.
