Have the keepalive promise return a boolean indicating whether it
detected a connectivity failure or not. Use this to only emit
CATCHUP if there was a connectivity error, to try & suppress
the state flip-flopping back & forth between CATCHUP and ERROR
in the case where we have connectivity but the sync is returning
and error for whatever reason.
