[Bug 1915849] [NEW] setting a bound port qos policy from empty to a policy with min bw rules does not update placement allocation

 

Public bug reported:

1) have a net with a qos policy set
2) create a port in that net without specific qos policy
3) boot a server with that port
4) set a specific qos policy on the port

Expected:
* The neutron port resource request is changed according to the new qos policy set on the port.
* The resource allocation in placement is changed according to the new qos policy set on the port.

Actual:
* The neutron port resource request is changed according to the new qos policy. So this is OK.
* But the allocation in placement still matches with the qos policy of the network not the qos policy of the port
