upgrading to Leap 15.4 first.

Conducted upgrade to Leap 15.4

zypper --releasever=15.4 ref && zypper --releasever=15.4 -n --no-refresh dup --auto-agree-with-licenses --replacefiles --download-in-advance --dry-run

and then installed more recent version of Java and service restart with

zypper -n in java-17-openjdk
systemctl restart jenkins

Then webUI of jenkins was reachable again. Then I opened
http://jenkins.qa.suse.de/updateCenter/ to install all pending updates. I also triggered runs of gnome_next-openqa and trigger-openQA_in_openQA-TW which both went fine.

To add the machine to monitoring I did the following changes

echo '10.160.0.207    salt' >> /etc/hosts
echo jenkins.qa.suse.de > /etc/salt/minion_id
systemctl enable --now salt-minion

and accept and apply salt from the master osd:

sudo salt-key -y -a jenkins.qa.suse.de
sudo salt 'jenkins*' state.apply test=True
sudo salt 'jenkins*' state.apply
sudo salt -C 'G@roles:monitor' state.apply

And now https://monitor.qa.suse.de/d/GDjenkins/dashboard-for-jenkins?orgId=1&refresh=1m shows monitoring results from jenkins.qa.suse.de

There was a problem with the hostname fixed in https://gitlab.suse.de/qa-sle/qanet-configs/-/merge_requests/41/diffs?commit_id=96dedfcafaf079b0b0a94f8d52f9b3b9afc18032
