Public bug reported:
I got an error in the test_distributed_port_binding_deleted_by_port_deletion
test on my CI run [1].
Also I found the same failure in another CI run [2]

I have spent some time and seem to have found the reason for this behavior on
python 3.10.
First of all, since python3.10 we get a warning when using ssl.PROTOCOL_TLS [3]:
[root@node0 neutron]# python
Python 3.10.8+ (heads/3.10-dirty:ca3c480, Nov 30 2022, 12:16:40) [GCC 4.8.5

>>> ssl.SSLContext(ssl.PROTOCOL_SSLv23)
<stdin>:1: DeprecationWarning: ssl.PROTOCOL_TLS is deprecated

>>>
I also found that the `test_ssl_connection` test case affects catching warnings
in the test_distributed_port_binding_deleted_by_port_deletion test case.
I was then able to reproduce the issue like this:
[root@node0 neutron]# cat run_list.txt
