Support SRIOV interface attach and detach
For attach:
* Generates InstancePciRequest for SRIOV interfaces attach requests
* Claims and allocates a PciDevice for such request
For detach:
* Frees PciDevice and deletes the InstancePciRequests
On the libvirt driver side the following small fixes was necessar:
* Fixes PCI address generation to avoid double 0x prefixes in LibvirtConfigGuestHostdevPCI
* Adds support for comparing LibvirtConfigGuestHostdevPCI objects
* Extends the comparison of LibvirtConfigGuestInterface to support
macvtap interfaces where target_dev is only known by libvirt but not
nova
* generalize guest.get_interface_by_cfg() to work with both
LibvirtConfigGuest[Inteface|HostdevPCI] objects
Implements: blueprint sriov-interface-attach-detach
