Add pod for the hypervisor and other fixes

* Add pod creation, so that when we remove the hypervisor
  then all the VMs also get removed automatically
* virtinst is only used when creating/installing VMs, so
  only install on hypervisor nodes
* Only grab the top vlan if we have 2, this typically
  means that we have an ipv4 and ipv6 IP. Could probably
  do this better, but keep it simple for the time being
