When nova needs to create ports in Neutron in a network that has minimum
bandwidth policy Nova would need to create allocation for the bandwidth
resources. The port creation happens in the compute manager after the
scheduling and resource claiming. Supporting for this is considered out
of scope for the first iteration of this feature.
To avoid resource allocation inconsistencies this patch propose to
reject such request. This rejection does not break any existing use
case as minimum bandwidth policy rule only supported by the SRIOV
Neutron backend but Nova only support booting with SRIOV port if those
ports are precreated in Neutron.
