-- Creates a @RuleGroup@ . A rule group is a collection of predefined rules that you add to a web ACL. You use 'UpdateRuleGroup' to add rules to the rule group.
--
--
-- Rule groups are subject to the following limits:
--
--     * Three rule groups per account. You can request an increase to this limit by contacting customer support.
--
--     * One rule group per web ACL.
--
--     * Ten rules per rule group.
