// Creates a RuleGroup per the specifications provided. A rule group defines a

	// When you add or modify the rules in a rule group, WAF enforces this limit. You
	// can check the capacity for a set of rules using CheckCapacity . WAF uses WCUs to
	// calculate and control the operating resources that are used to run your rules,
	// rule groups, and web ACLs. WAF calculates capacity differently for each rule
	// type, to reflect the relative cost of each rule. Simple rules that cost little
	// to run use fewer WCUs than more complex rules that use more processing power.
	// Rule group capacity is fixed at creation, which helps users plan their web ACL
	// WCU usage when they use a rule group. For more information, see WAF web ACL

	// instance. To work with CloudFront, you must also specify the Region US East (N.
	// Virginia) as follows:
	//   - CLI - Specify the Region when you use the CloudFront scope:
