@MartinBasti I see you created this PR against master, don't we want to use the feature_cachi2 branch?

IIRC we wanted this change to go to master, because it's relevant for Cachito as well.

Some projects (OpenScanHub) do rebuilds of OSBS builds and they depend on the env vars and config files from Cachito. When we decommission Cachito, they will no longer be able to use them. If we start uploading them to Brew now, they will be able to rebuild things up to half a year old (let's say we will decommission Cachito in half a year).
