Support both FWaaS v1 and v2 in OpenLab

Some SDK/Tools project still support FWaaS v1, like
terraform-provider-openstack, even if OpenStack FWaaS team have not
added any new feature into v1. OpenLab should support to run tests
against FWaaS both v1 and v2, let SDK/Tools project to choose run which
one.

Fixes: apache#43
