I made some updates to the README that I never committed.
I'm probably going to change some of this but it's more useful
with these additions than without.
Updating README for instructions on how to use the control-repo
by putting it in your own git server and then using the r10k
answers during installation of PE.
Removing the manifest for configuring r10k using zack/r10k.
Added a role that can be used to bootstrap an all-in-one PE
installation.
