vArmour gateway agent and FWaaS driver
This patch enables vArmour's routing and firewall services to be deployed in openstack environment. - as gateway for internal networks - support SNAT and DNAT (floating IP) - FWaaS services Implements: blueprint varmour-fwaas-driver Change-Id: I6ddfa3137ed7e2a3fcf16a764d1340a8eae9359a
