    Run an interactive Python shell, with the cluster accessible via
    the ``ctx`` variable.

    Hit ``control-D`` to continue.

    This is also useful to pause the execution of the test between two
    tasks, either to perform ad hoc operations, or to examine the
    state of the cluster. You can also use it to easily bring up a
    Ceph cluster for ad hoc testing.

    For example::

        tasks:
        - ceph:
        - interactive:
