[OVN] "test_agent_show" failing, agent not found

[Rodolfo Alonso]

Related to https://bugs.launchpad.net/neutron/+bug/1897921

This bug is very similar to LP#1897921 but is slightly different; that's why I've opened a second bug. In this case, the error is happening when the OVN driver tries to retrieve the agent [1]. The agent is not found using the OVN plugin neither the ML2 plugin [2].

    Make test_agent_show only look for its own agents

    Since plugin agents are a global resource, relying just on the
    'type' field for test_agent_show may end up finding an agent that
    we don't know about, and that agent could be deleted by another
    test. This reworks test_agent_show to sepecifically look for its
    own OVN controller agent and test agent.

    This also adds the 'id' field to the returned agent_status from
    create_or_update_agent() to make it possible to look for the agent
    that was just created.
