Modify qpush/qpop idempotent operations to return success
Modify qpush/qpop such that idempotent instances of the operations
return success. That is, repeated qpush -a, qpop -a, qpush patch-name
or qpop patch-name will return success. The end goal of each of these
operations is to reach a particular state. Whether or not the patches
were already applied does not affect that state or operation status.
Likewise, be careful to retain the error status on a qpush/qpop
without arguments when the end/beginning of the series has been
reached.
