Backends such as OVN will create a port to be used by the metadata agent upon creating a network. That port will be substract from the tenant's quota and that was what was previsouly causing this test to fail in OVN. This patch is changing the approach to make it more generic by calculating the number of used ports based on the number existent after the network is created and prior to the new port being created. A similar approach was used in the patch https://review.openstack.org/#/c/559758/ for the same reason. Change-Id: I952d31c4473159a3fdd0552eeae98750ee27a1f9
