dsvm failure: devstack plugin is not enabled to reuse multiple times

[Tung Doan]

Recently, OpenStack Devstack does not allow plugin to re-use multiple times [1]. That's why dsvm job in Tacker failed [2].
Error:
[ERROR] /opt/stack/new/devstack/functions-common:1775 Plugin attempted to be enabled twice: tacker git://git.openstack.org/openstack/tacker master

    Fix dsvm failure caused by devstack plugin and event/auditing func.

    This patch will fix dsvm failure:
    1. The new changes in devstack [1]. Whereby, plugin was not enabled
    to use multiple times. Currently, almost functions like fixup_quota,
    add_key and add_secgrp enable plugin which runs multiple times.
    2. Some functional tests were not working with event/auditing function.
