  - Remove ugly code in odl plugin

    JIRA: -

    Remove the ugly code in odl plugin. These code may cause tempest failures while
    running daily functest. These failures cannot be reproduced locally but only in
    daily functest. So we proposed this patch to improve our code and verify whether
    it can fix the failures in tempest.
