Updated all in one Rackspace Private Cloud Installation


This update makes it possible to deploy the rackspace Private Cloud using 
in a more consumable fashion. Here are the highlights 

Overview:
* Now supports RHEL/Ubuntu/CentOS
* Now has the ability to change the default run lists
* Now allows the user to for the script and repoint it to a different script if they so choose
* Installation template is now a lot smaller as the script with the meat of the install is an external resource.

New abilities in Script: 
* The new installer now has better support for gauging system resources. This is required because new cloud server images do not come with a swap partition and when a user is running everything in one server the likelihood the system will swap is high.
* Dependencies in the script are better resolved
* MOTD is now set with information on post build / deployment which also effects the main login page even in console.
