Update conductor to write engine.version file (#163350)

Browse Source 
This adds a new phase to the conductor after applying cherrypicks, to
update the engine.version file with the revision from the previous
commit. Note, this will produce a different PR, because it has to be in
a different commit after squash & merge.
