-- Permanently deletes a 'RuleGroup' . You can't delete a @RuleGroup@ if it's still used in any @WebACL@ objects or if it still includes any rules.
--
--
-- If you just want to remove a @RuleGroup@ from a @WebACL@ , use 'UpdateWebACL' .
--
-- To permanently delete a @RuleGroup@ from AWS WAF, perform the following steps:
--
--     * Update the @RuleGroup@ to remove rules, if any. For more information, see 'UpdateRuleGroup' .
--
--     * Use 'GetChangeToken' to get the change token that you provide in the @ChangeToken@ parameter of a @DeleteRuleGroup@ request.
--
--     * Submit a @DeleteRuleGroup@ request.
