Title:
  LbbasV2-Session persitence HTTP_COOKIE-no cookie sent to client

Status in neutron:
  Expired

Bug description:
  we configured lbaasv2. LB , listener are created . Thenext step is the
  pool and members

  neutron lbaas-pool-create --lb-algorithm ROUND_ROBIN --listener
  5dd91024-148e-4d80-842f-3122725d0164 --protocol HTTP

  neutron lbaas-member-create 6b7b5daa-f773-46ca-8045-bb1f8ae8fcec
  --protocol-port 80 --subnet 67897b9a-e5dd-405a-80db-7e36ead62c27
  --address 192.168.1.3

  neutron lbaas-member-create 6b7b5daa-f773-46ca-8045-bb1f8ae8fcec
  --protocol-port 80 --subnet 67897b9a-e5dd-405a-80db-7e36ead62c27
  --address 192.168.1.4

  LB works properly.
  After updating the pool to use session persistence with HTTP_COOKIE we captured traffic on LB interface and saw that no cookie send towards the clients.
