    Add retries upon db error for deleting vip_port
    
    This is meant to handle cases where vip_port deletion fail with StaleDataError.
    StaleDataError happens when the you delete a loadbalancer, and then try
    to delete it's vip port.
    
    LBaaSv1:
    The retries where added by splitting delete_vip() to two functions:
    delete_vip() and _delete_vip_port(), and decorating the latter
    with @db_api.retry_db_errors
    
    LBaaSv2:
    The retries where added by splitting delete_loadbalancer() to two functions:
    delete_loadbalancer() and _delete_vip_port(), and decorating the latter
    with @db_api.retry_db_errors

Title:
  HAproxy scenario tests cleanup fail with a StaleDataError (LBaaSv1 and
  LBaaSv2)

Status in neutron:
  Fix Released

Bug description:
  Example for that error:
  http://logs.openstack.org/90/351490/4/check/gate-neutron-lbaasv2-dsvm-scenario-namespace-nv/8f1255a/logs/screen-q-svc.txt.gz#_2016-08-07_06_00_57_478

  This is easily reproduced locally on my devstack with neutron_lbaas.tests.tempest.v2.scenario.test_load_balancer_basic
  moreover, even if narrow the above mentioned scenario to only create a loadbalancer (with listener and pool and then, run the cleanup - the issue reproduces.

  This is blocking the gate-neutron-lbaasv2-dsvm-scenario-namespace-nv
  from properly indicate whether or not scenario tests fail for haproxy
  in namespace lbaas driver.
