    Fix Tempest and Unit tests

    This patch is a squash of two commits that fix both tempest and
    unit tests:

    1. Port Groups: Fix bug when updating a port to trusted

    When a normal port with port security enabled (ie. belonging to
    default drop Port Group) gets updated to a trusted port (ie.
    router port), the existing code won't remove the port from the
    Port Group so all traffic gets dropped.

    This patch fixes the issue by checking this condition in the
    update_port method of the ovn_client module.

    2. UT: Fix unit tests failures

    After 3316b45665a99b0f61e45a8c7facf538618861bf got merged in
    Neutron, our gate is blocked due to unit tests failing.
    After some debugging, it looks like no longer importing
    neutron.db.api is the culprit. This patch is importing it
    from our unit tests to unbreak the gate while the actual
    root case is determined.
