    Update git submodules
    
    * Update tooz from branch 'master'
      - Blacklist etcd3gw 0.2.6
    
        etcd3gw 0.2.6 was blacklisted in openstack/requirements [0], because
        that version has a bug [1].
    
        tooz does not use openstack/requirements' upper constraints, so the
        same blacklisting needs to be introduced here in setup.cfg.
