Multi-node Controller script

Hey Kord
I have created a script that installs the controller in one shot with only 4 inputs at the beginning of the script. Inputs are nic, host name, username, and email. 

It all seems to work except the last sed input under HORIZON that sets "openstack_host = "$ctrl_name"" It is struggling with escaping the double quote.

If you set that manually then reboot it seems to work.
