Public bug reported:

In SRIOV scenario, it is a common use case that a VM has two ports and
users want to have the two ports scheduling to two different PFs for
redundancy.

The proposal for Neutron is to introduce a new key 'anti_affinity_group'
in binding:profile. The value of 'anti_affinity_group' is a unique ID
for grouping neutron ports. Nova is responsible to schedule ports that
has the same 'anti-affinity_group' to different PFs.
