libvirt: pass Host object into firewall class

Instead of passing in a get_connection callback function,
give the firewall class impls direct access to the new Host
object instead. Make use of the fakelibvirt fixture to
avoid needing to mock out the libvirt APIs directly.

Cleanup in test_availability_zone not to use wsgi_app

In API unit testing, making call through WSGI is little bit overhead,
wherever applicable, unit tests can make direct call to controller
methods.
Some unit tests need WSGI call to tests more than one plugin together.

This patch makes above cleanup in test_availability_zone.

Partially implements blueprint v2-on-v3-api
