Branch update utility

This script was created to rapidly interate through a repo_package file
that contains git sources and set the various repositories inside to
the head of given branch via the SHA. This makes it possible to update
all of the services that we support in an "automated" fashion.

Partially implements: blueprint master-kilofication
