Balazs Gibizer 1c056c384d Fallback to same-cell resize with qos ports
The cross-cell resize code does not consider neutron ports with resource
request. To avoid migration failures this patch makes nova to fall back
to same cell resize if the instance has neutron ports with resource
request.

When the tempest test coverage was added for resize and cold migrate
with neutron ports having QoS minimum bandwidth policy rules we
discovered that the cross cell resize code path cannot handle such ports.
See bug https://bugs.launchpad.net/nova/+bug/1907522 for details. A fix
was implemented that makes sure that Nova falls back to same-cell resize if
the server has such ports.
