Intermittent failures due to "Can't connect" errors
Sometimes Gitlab CI job shows "Can't connect: Temporary failure in name resolution", and sometimes the job then fails.
The error presumably comes from openqa-cli
tool which we run in a loop to poll job status. The message comes from here in Mojo framework: https://github.com/mojolicious/mojo/blob/75124ab7b0e27dc647304067110c2effacc453cf/lib/Mojo/IOLoop/Client.pm#L92
It's not clear how we could get extra diagnostics here. Presumably the runner has a DNS resolution error that means it can't access openqa.gnome.org.
