* Remove network integration group_vars/host_vars
We use our own inventory in DCI, which is passed to ansible-test
with --inventory.
However, as the working directory of ansible-test is set to
test/integration, ansible consumes the repo group_vars/host_vars.
That imposes a problem, since they have greater precedence to
inventory variables.
Let's just remove group_vars/host_vars so end-users can assume
those vars can be used, the inventory and group/host vars are
environment dependent, each user should create their own.

We need to use IP address, as inventory_hostname returns an UUID from
openstack.py inventory in our CI.
Also, commenting the username/pass as we set them in the inventory (we shall
change this in the future).
