vsphere: Support multiple NIC backings

Browse source 
A bit of background: currently fog supports Network[1], but there's also
DistributedVirtualPortgroup[2] which extends Network.

With this commit create_vm tries to detect if the network is a
DistributedVirtualPortgroup. If it is it will create the appropriate backing
(VirtualEthernetCardDistributedVirtualPortBackingInfo[3]). If it's not it will
fall back to the regular backing (VirtualEthernetCardNetworkBackingInfo[4]).

Known issues:
* It is possible for an administrator to assign network permissions to a
  DistributedVirtualPortgroup[2], but not to the DistributedVirtualSwitch[5].
  In that case you can't read its UUID and it fails with an exception.
