    'ceilometer-polling' should fail with no valid pollsters

    The command 'ceilometer-polling --pollster-list' should fail with
    invalid pollsters.

    When executing the command 'ceilometer-polling --pollster-list' with
    a wrong pollster like aaa, it still executes and no error will
    be shown. It occupies the system resources and shows no errors.

    Remove the test case for
    "ceilometer-polling --polling-namespaces ipmi" in the upgrade.sh.
    In the test environment, the ipmi is not ready. It should fail.
