When running Tempest test 'tempest.api.network.test_ports.PortsTestJSON.test_create_port_in_allowed_allocation_pools' on a 3 controllers infra, we have this error: 'No more IP addresses available on network UUID'.
As we have 3 controllers, each one pick an IP and the pools have no more IP available.
In the code, the function created a new subnet with only 3 IPs available for the allocation pools. (ex: 192.168.1.4 - 192.168.1.6).
