Disable qos resize tempest test for nova-multi-cell job

Browse Source 
It turned out that during the qos resize work we did not implemented
support of cross cell resize with qos ports. Tempest test coverage for
the resize and migrate is landed recently that made the nova-multi-cell
job to fail.

So this patch disables the qos resize and migrate tempest tests for the
nova-multi-cell job to unblock the gate.

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.
