Adds installer/updater for the Admin VM

This commit adds a script and Puppet module that can be used to create
or update an Admin VM. Most users should get their initial Admin VM from
the project's web site and should not attempt to use the installer.
However, they should be able to use the updater for their existing Admin
VM. Contributors to this repository can now make code changes that
require Admin VM configuration changes by modifying the Puppet module.
