push: rename config variable for more general use

The 'pushNonFastForward' advice config can be used to squelch several
instances of push-related advice.  Rename it to 'pushUpdateRejected' to
cover other reject scenarios that are unrelated to fast-forwarding.
Retain the old name for compatibility.
