    Fix taskflow parameters for manage_existing

    Make optional_args not a required parameter.

    Taskflow validates that these parameters match
    between execute and revert. Since optional_args
    is not used, we can fix this by making it not
    required in revert.

    This fixes the taskflow validation failure, we
    should investigate further into whether this
    flow works completely correctly.
