CentOS Stream 8 and Fedora 37 are EOL and their jobs are just
failing.
Disabled the Centos Stream 8 job, and marked the Fedora Core 37 job
as non-voting fo the time being so we are encouraged to fix by adding
a FC 38 or FC 39 job.
Also removing CS8 and Fedora jobs from dib-functests, and
setting the debian functional build to assume yes to try and
minimize prompting on package upgrades.
