Bug description:
  This SRU is related to bug #1918145, which reported slow RBAC queries
  in Neutron. The performance issue was addressed upstream through
  modifying the SQL queries [1] and using a GROUP BY clause in the
  Neutron lib [2].

  Looking at the Ubuntu Neutron lib package [3], this group by
  optimization clause [2] is missing in stable/yoga and stable/antelope,
  although it present in Zed, Bobcat, and Caracal

  by optimization change that is missing from yoga and antelope)
