Add support for code manager which will replace zack r10k

Add pltraing-rbac module
Added a new profile for code_manager that:
 - creates a service users for code manager
 - creates a token for that service user
 - creates a hook on a git server using the token

Turns out that the file function in puppet cannot read files in
/root.  The pe-puppet user needs read permissions on the file
and traversal on the directory which giving to /root would
probably be a bad idea.  So, I just put the file containing
the token in /etc/puppetlabs/puppetserver since I'm not sure
where would be better.
