Merged requested to merge tadej/athena:ci-meta-diff into master
meta-diff in all tests with reference but reco (will be added separately). Only Athena release, file size and file GUID are ignored. It only runs if CA is not overridden (so the default tag that is also used as a reference) as we do not plan to have 100 % matching metadata.
Will need some reference updates due to AMI tag changes, but let's not ignore it as it will also validate the machinery.
