    Add comprehensive checks for container restarts

    When adding a dashboard to grafana the containers aren't restarted when
    they should be. This is due to a bug in Kolla where the logic to
    determine whether or the container needs to be restarted fails in the
    case where the file does not exist in the container. This patch adds
    more comprehensive checks for container restarts in the set_configs.py
    file. This patch also adds a test to ensure that the functions work as
    expected.
