Title:
  Neutron does not refresh mysql connection when HA failover happens

Status in neutron package in Ubuntu:
  Incomplete

Bug description:
  Config:

  Three MySQL nodes using percona (percona-cluster charm vai juju)
  Two Neutron nodes providing network services to an openstack HA deployment (all done via juju).

  Issue:

  While testing failover of MySQL, we noticed that we could no longer
  create instances of any sort.  Looking further it looks like neutron-
  server can not talk to the mysql server that is currently active
  (using the assigned VIP).

  Attached is the server log from neutron-server.

  Restarting neutron-server resolved the issue for us.
