Issue description

OVN assigns IPs sequentially. That means if I create two containers then delete one and stop/start the other one, the latter changes IP.

Steps to reproduce

1. lxc launch ubuntu:22.04 test-sticky-ip lxc launch ubuntu:22.04 test-sticky-ip-2

| test-sticky-ip   | RUNNING | 10.47.208.3 (eth0)  |      | CONTAINER | 0         | host3 |
+------------------+---------+---------------------+------+-----------+-----------+-----------------+
| test-sticky-ip-2 | RUNNING | 10.47.208.4 (eth0)  |      | CONTAINER | 0         | host2 |

2. lxc delete test-sticky-ip --force
3. lxc stop test-sticky-ip-2
4. lxc start test-sticky-ip-2
5. Result test-sticky-ip-2 get IP previously allocated for test-sticky-ip

| test-sticky-ip-2 | RUNNING | 10.47.208.3 (eth0)  |      | CONTAINER | 0         | host2 |
