    Update git submodules
    
    * Update oslo.messaging from branch 'master'
      - Python 3.9: isAlive is removed
    
        The Threading method isAlive was deprecated a long time ago, in the favor
        of is_alive(). Though in Python 3.9, isAlive is removed. We must switch
        to it. Note that is_alive() is available at least in Python 3.5 (I tried)
        and probably even earlier, so switching to is_alive() is not a problem
        for the Python interpreter versions currently supported by OpenStack.
