Deployment backend is exposed via HTTPs with self-signed certs and clients are exposed via trusted certs from letsencrypt. How can I solve the issue?

[Shuai Qian (iauhsnaiq)]

this is a bug of release-2023.1 in kolla-ansible, so if you deploy other versions, you wouldn't hit this.

and the tmp solutions for the issue is as following:

1. add the following 2 lines into /etc/kolla/skyline-apiserver/gunicorn.py
(these two files should be in skyline_apiserver container, generated by kolla-ansible.)
```
keyfile = "/etc/skyline/certs/skyline-key.pem"
certfile = "/etc/skyline/certs/skyline-cert.pem"
```

then /etc/kolla/skyline-apiserver/gunicorn.py is like
# something
bind = "172.16.150.185:9998"
workers = 5
worker_class = "uvicorn.workers.UvicornWorker"
timeout = 300
keepalive = 5
reuse_port = True
proc_name = "skyline"
keyfile = "/etc/skyline/certs/skyline-key.pem"
certfile = "/etc/skyline/certs/skyline-cert.pem"
# something

2. restart skyline-apiserver container.
