    Update git submodules
    
    * Update openstack-ansible-os_nova from branch 'master'
      - Merge "Make possible to set nova_libvirt_images_rbd_pool to empty string"
      - Make possible to set nova_libvirt_images_rbd_pool to empty string
    
        Checking if nova_libvirt_images_rbd_pool is defined leaves us without
        an opportunity to disable ceph usage for specific node.
        Instead of that we will use bool filter, which will be true if line
        is not empty, and false if it is. That way by setting variable to empty
        string in host_vars we can disable all relevant options for specific node
