/**
 * Networking (Neutron) FwaaS FirewallPolicy Policy Extension API
 * 
 * Represents an ordered collection of FirewallPolicy rules. A FirewallPolicy policy can be shared across tenants. 
 * 		Thus it can also be made part of an audit workflow wherein the firewall_policy can be audited by the 
 * 		relevant entity that is authorized (and can be different from the tenants which create or use the FirewallPolicy policy).
 * 
 * 
 * 
	 * The FWaaS extension provides OpenStack users with the ability to deploy firewalls to protect their networks. The FWaaS extension enables you to:
	 * 

	 * 		Apply FirewallPolicy rules on traffic entering and leaving tenant networks.
	 * 		Support for applying tcp, udp, icmp, or protocol agnostic rules.
	 * 		Creation and sharing of FirewallPolicy policies which hold an ordered collection of the FirewallPolicy rules.
	 * 		Audit FirewallPolicy rules and policies.
	 *
