Failure to obtain Kerberos ticket doesn't block

[sentry-io]

Sentry Issue: PCKT-002-PACKIT-SERVICE-8H6

Usage: osh-cli version-diff-build [options] <args>

osh-cli: error: You are not authenticated. Please obtain Kerberos ticket or specify username and password.

This was apparently a flake on the side of Fedora Infra (there were some networking changes / redeployments announced by Fabian on Slack). We have failed to obtain the Kerberos ticket, but at the same time, this problem was not blocking, i.e., the execution continued all the way to the running osh-cli which then failed because of the missing ticket.

We should be able to detect this issue in a better way, since it can indicate an outage or disruption on the Fedora Infra and also it could be raised from different jobs (e.g. Koji builds, Bodhi updates and sync-release actions require the Kerberos ticket to be present).

TODO:

• Catch, retry, and re-raise (if needed) before running the osh-cli

Looks like a flake, since the ticket has been obtained. However I would expect this to fail a bit sooner than on the osh-cli because of the missing Kerberos ticket.
