A deeply misguided effort to move all exceptions out of the
heat.engine.resource module, where they belong, and into the
heat.common.exception module, where they largely do not, broke the API for
third-party resource plugins. Unfortunately this happened a couple of
releases back already, so we can't simply put UpdateReplace back where it
belongs as that would also break the de-facto third-party API.
This change adds an alias in the correct location and a comment indicating
that it will move back at some time in the future. It also switches all of
the in-tree uses back to heat.engine.resource.UpdateReplace, in the hope
that third-party developers will be more inclined to copy from that.
This reverts commit 4e2cfb991a.
