Add range support to all address fields in pci_passthrough_whitelist

[Moshe Levi]

This way a user will be able to exclude a specific VF.

Example of func range:
1 . pci_passthrough_whitelist = {"address":"*:02:00.2-4","physical_network":"physnet1"}
2. pci_passthrough_whitelist ={"address":"*:02:00.2-*","physical_network":"physnet1"}

Example of slot range:
1. pci_passthrough_whitelist ={"address":"*:02:02-04.* ","physical_network":"physnet1"}
2. pci_passthrough_whitelist {"address":"*:02:02-*.*","physical_network":"physnet1"}

same will be for bus and domain.

This looks like a wishlist bug to me, typically anything that says 'add support for' is a blueprint in bug's clothing.
