Code Issues Proposed changes

Update git submodules 

* Update oslo.messaging from branch 'master'
  - Merge "Fix switch connection destination when a rabbitmq cluster node disappear"
  - Fix switch connection destination when a rabbitmq cluster node disappear
    
    In a clustered rabbitmq when a node disappears, we get a
    ConnectionRefusedError because the socket get disconnected.
    
    The socket access yields a OSError because the heartbeat
    tries to reach an unreachable host (No route to host).
    
    Catch these exceptions to ensure that we call ensure_connection for switching
    the connection destination.
    
    POC is available at github.com:4383/rabbitmq-oslo_messging-error-poc
    
    Example:
        $ git clone git@github.com:4383/rabbitmq-oslo_messging-error-poc
        $ cd rabbitmq-oslo_messging-error-poc
        $ python -m virtualenv .
        $ source bin/activate
        $ pip install -r requirements.txt
        $ sudo podman run -d --hostname my-rabbit --name rabbit rabbitmq:3
        $ python poc.py $(sudo podman inspect rabbit | niet '.[0].NetworkSettings.IPAddress')
    
    And in parallele in an another shell|tmux
        $ podman stop rabbit
        $ # observe the output of the poc.py script we now call ensure_connection
    
    Now you can observe some output relative to the connection who is
    modified and not catched before these changes.
