When using nova version 2.56, tempest failed

[Min Li]

I did this test based on the watcher victoria version，since the Nova version Watcher neede is at least 2.56, I configured CONF.compute.min_microversion to 2.56, but in the scenario test, the following error occurred:

  File "/usr/local/lib/python3.8/dist-packages/watcher_tempest_plugin/tests/scenario/base.py", line 238, in _create_one_instance_per_host_with_statistic
    instance = self.create_server(

    self._error_checker(resp, resp_body)

    raise exceptions.NotFound(resp_body, resp=resp)
tempest.lib.exceptions.NotFound: Object not found
Details: {'code': 404, 'message': 'The resource could not be found.'}

This is because the "os-networks" api was deprecated since Nova version 2.36. Does this mean that watcher-tempest-plugin is not compatible with tempest?
