DEPRECATION: In addition to an object with the above fields, the ``test``
key currently also supports ``bool``, which maps to ``enabled``, but this is
deprecated and will be removed. The ``cleanup`` option below is set to true
in this case for backward compatability.

The preferred way to achieve test cleanup is to add a pre-upgrade delete
action on the test pod, which allows for debugging the test pod up until the
next upgrade.
