Create CentOS & Wheezy minion bootstrap script

As well as installing our minion (#6855), the bootstrap script should set the master address so that the minion can start talking to the calamari server right away. In order for it to know the address of the master, the script could be served as a simple django view, with a template that substitutes the master address into the script.
