Subject: [PATCH] Ignore failing pods and jobs from NC installation
Currently, Nextcloud installation is a pain where a lot of jobs and pod
fail until NC is finally installed. Still they show up in proemetheus and
create noise, why we ignore them in this check.
Once we achieve a better NC installation we should revert this.
Closes: #379
