discovery: diet discovery.prepush from non-discovery code

The ``discovery.prepush`` function was doing multiple things not related to
discovery. This changeset move some code into the ``localrepo.push`` method. The
old ``discovery.prepush`` function jobs is now restricted to checking for
multple head creation. It was then renamed ``discovery.checkheads``.

This new ``discovery.checkheads`` function may receive several other changes in
the future but we are a bit too much near the freeze for a wider refactoring.
