  - Bug fix: Add iteration to check RSP config in ODL

    JIRA: SFC-110

    Sometimes the test is quicker than ODL and when it checks the configured RSP,
    that configuration has not yet been submitted in ODL, thus ODL replies with an
    empty list. We add an iteration to try again for a couple of times
