Title:
  Change a QoS policy on a bound port does not handle minimum bandwidth
  direction change

Status in neutron:
  Fix Released

Bug description:
  When changing the QoS policy having a minimum bandwidth rule on a
  bound port to another policy where the direction of the min bw rule
  has changed then neutron accepts the request but fails to update the
  bandwidth resource allocation in placement accordingly.

  Reproduction
  ------------

  Here is a tempest test reproducing the issue
  https://review.opendev.org/c/openstack/tempest/+/809198

  Expected behavior
  -----------------
  Neutron allocates resources in placement according to the new direction

  Actual behavior
  ---------------
  Neutron does not move the resource allocation from one resource class to the other (representing the directions)

  Affected version
  ----------------
  Reproduced on recent master in devstack.

  stack@master0:~/neutron$ git log --oneline
  6db2619628 Merge "[DVR] Set arp entries only for single IPs given as allowed addr pair"

  Bug probably exists since neutron added support for changing QoS
  policy on bound ports with minimum bandwidth rules.
