Two api tests for 'firewall insertion mode' feature

Some time ago the feature called 'fwaas insertion mode' was merged.
It allows to associate a firewall with routers.

The patchset adds two api tests:
* Create firewall assiciated with a router, add another router
to the firewall, remove old one
* Create firewall assoicited with a router, try to create new
firewall on the same router
