Add support for PCI passthrough and SR-IOV
Add ability for VMs to access PCI devices directly.
Some implementation details:
- add new params into instance type's extra-data, specifying type/class of pci_passthrough device, possibility to use SR-IOV and number of devices to associate
- on each compute node specify list of devices available for PCI passthrough
- libvirt & other compute drivers to be modified and perform following:
* find list of available (non-used) PCI devices or VFs
* assign device to instance (modify template & xml dict)
* store (in instance meta-data?) information about used devices
