Skip test_qos_min_bw_allocation_basic when not supported

The test_qos_min_bw_allocation_basic relies on a feature [0] which is
not supported by all Neutron backends. This test for example will fail
for OVN until [0] is implemented for it.

This patch makes the test skippable instead of failing when the backend
does not support it.
