Public bug reported:

Similar to https://bugs.launchpad.net/neutron/+bug/1774460, we still
facing the error with neutron on Caracal.

we just migrated using new openstack CLI tools, and when triggering pagination for both Nova and Neutron, we noticed that they are returning http href link although they are expecting https, causing failure:
```
openstack port list
Failure: Unable to establish connection to http://openstack....example.com:9696/v2.0/ports: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')). Retrying in 0.5s.1 retries left
Unable to establish connection to http://openstack.....example.com:9696/v2.0/ports: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
```

when I run openstack port list --debug, I see the first bulk hits neutron with 
REQ: curl -g -i -X GET "https://openstack...example.com:9696/v2.0/ports?...";
and in the RESP BODY: `"href":"http://openstack.bve.example.com:9696/v2.0/ports?...`
which caused neutron failed to provide response following that. 

I've validated it is problem even with
[oslo_middleware]
enable_proxy_headers_parsing = True

in neutron.config. I validated that Nova is having same issue, and it could be solved with 
[DEFAULT]
osapi_compute_link_prefix = https://openstack...

However, the option doesn't exit in neutron config.
