    Debian: Fix nova actions

    Since the platform migration to Debian, it was observed that the
    following Nova actions stopped working:
      - pause;
      - unpause;
      - suspend;
      - resume;
      - live-migration.

    The reason behind that is that some packages related to Nova, which have
    already been migrated to Debian, still have some incompatibilities with
    Python 3. Consequently, whenever these Nova actions were executed, some
    exceptions occurred on the nova-api-proxy and NFV side, preventing them
    from working.

    Therefore, this change aims to improve this compatibility.

    Most of the changes were necessary due to the fact that in Python 3
    there is more of a distinction between `bytes` and `str`, whereas in
    Python 2 `bytes` is just an alias for `str`.

    Test Plan (on AIO-DX):
    PASS - Successfully perform a VM pause, unpause, suspend, resume.
    PASS - Successfully perform a VM live-migration.
