Code Issues Proposed changes

Update git submodules 

* Update networking-baremetal from branch 'master'
  - Set amqp_auto_delete=true for notifications transport.
    
    ironic-neutron-agent uses oslo.messaing notifications
    to manage the hash ring members. Each listener uses a
    pool, to ensure all instances of the agent recived
    notifications from all other isntances of the agent.
    
    The pool used is a random uuid that is generated on
    startup, and on restart a new uuid is generated.
    
    In the messaging backend each pool creates a separate
    queue. When the agent is restarted this queue is not
    removed, and since the uuid is regenerated for the
    restarted agent the messaging backend keep publishing
    messages to the "old-uuid" queue as well as the
    "new-uuid" queue. The problem is that the "old-uuid"
    queue is no longer consumed, so it continues to grow
    and cause high RAM usage in the message broker
    back-end.
    
    To fix this set the queues to auto_delete so that
    they are deleted automatically when no consumers are
    active.
