pci: Clarify SR-IOV ports vs direct passthrough ports
This patch clarify for what type of ports
detach/attach pci device is needed and for what type of
port we just need pci request. To avoid confusion this
patch introduce 2 type of ports list VNIC_TYPES_SRIOV
and VNIC_TYPES_DIRECT_PASSTHROUGH. The VNIC_TYPES_SRIOV
are ports which require pci request, while
VNIC_TYPES_DIRECT_PASSTHROUGH ports require pci device
attach/detach from libvirt dom. VNIC_TYPES_DIRECT_PASSTHROUGH
is subset of VNIC_TYPES_SRIOV.

Title:
libvirt: Snapshot and resume does not work for instances with some SR-
IOV ports
Status in OpenStack Compute (nova):
Fix Released
Bug description:
libvirt driver methods that are used for determining whether a port is
an SR-IOV port do not check properly for all possible SR-IOV port
types:
https://github.com/openstack/nova/blob/f15d9a9693b19393fcde84cf4bc6f044d39ffdca/nova/virt/libvirt/driver.py#L3378
should be checking for VNIC_TYPES_SRIOV instead.
This affects snapshot and suspend/resume functionality provided by the
libvirt driver, for instances using non-direct flavors of SR-IOV
