staypuft: fix deployment issues

This commit corrects the NAT setup on the foreman machine so that the
provisioned machines can access the network through it. Otherwise this would
require adding a few networks and assigning them in the installer.

staypuft: image size and removal, subscription fixes

* increasing image size, otherwise there's not enough space with LVM for
  mongodb to start (see https://bugzilla.redhat.com/show_bug.cgi?id=1125374)
* removing the deploy vm disks (the size change won't take effect without it)
* enable the subscription upon registration (necessary for having RHEL7 repos
  on the provisioned systems)
