update-osconfig-script: Added a temporary util to upgrade osconfig

Added a temporary util that allows us to upgrade osconfig with one
command.  This is something similar to what I have as part of my
personal set of tools.  I figured since osconfig is so arduous, it
might be better to have this so that maintainers can do all the steps
in one fell swoop.
