      We added retry logic into the OplogFetcher in SERVER-25702 to increase robustness of initial sync.  By doing so, however, we also added these restarts into regular steady state replication.  This can slow down sync source resolution unnecessarily when one node is unavailable but other nodes would be able to serve as the sync source.
