manage tls certificates on o3/ariel directly with dehydrated size:M

Description
Motivation¶
(We got informed)[[https://app.slack.com/client/T02863RC2AC/C04MDKHQE20/thread/C04MDKHQE20-1688735468.778099]] that ariel/o3 will have no hydra/ha-proxy setup in the new location. Therefore we need to handle our tls certificates for nginx on our own in the future.
Acceptance criteria¶
- AC1: openqa.opensuse.org has a valid certificate requested by the webhost itself
- AC2: the process is fully automated and certificate renewal requires no human interaction
- AC3: Any generalizable config snippets are in github.com/os-autoinst/openQA/
Suggestions¶
- Install an Lets Encrypt compatible client on ariel (see https://wiki.archlinux.org/title/Transport_Layer_Security#ACME_clients for a list) - nsinger recommends (dehydrated)[[https://github.com/dehydrated-io/dehydrated]]
- Adjust nginx to serve the ACME challenges and reconfigure existing entries to use that new certificate
- Feel welcome to experiment on o3 as long as you monitor closely that everything still works as expected or is quickly reverted on problems
- Submit any generalizable config snippets into github.com/os-autoinst/openQA/, e.g. as commented nginx config templates

Thank you. lhaleplidis now stated that he plans to work with a proxy so the task is still up for discussion.
We could already set it up anyway (in parallel to the existing infra). Then we would be prepared for every possibility.
Yes, I think we should do that
I was thinking about this and realized that we have to see how the current webserver proxy is setup. If it forwards requests to http://openqa.opensuse.org/.well-known/acme-challenge/ we can already create valid certificates. Otherwise we have no way to respond so Challenges from lets encrypt and won't be able to issue a certificate on our own.

Installed dehydrated and adjusted /etc/nginx/vhosts.d/openqa.conf to include conf.d/dehydrated.inc which basically just serves challenges contained in /var/lib/acme-challenge from http://openqa.opensuse.org/.well-known/acme-challenge - it is the default location from dehydrated so no further configuration needed. After running:
root@ariel# dehydrated --display-terms
root@ariel# dehydrated --register --accept-terms
I received a valid certificate for o3:
ariel:/etc/dehydrated/certs/openqa.opensuse.org # tree .

I also added a crontab as root to refresh the certificate daily:
0 0 * * * /usr/bin/dehydrated --cron
also adjusted deploy_cert() in /etc/dehydrated/hook.sh to reload nginx after a certificate got renewed
