Jakub Rusz efbd5ebd7b ci/tests: Change the way artifacts are collected
We want to be able to safely gather any artifacts without worrying about
any possible secrets leaking. Every artifacts that we want to upload
will now have to be placed in /tmp/artifacts which will then be uploaded
to S3 by the executor and link to the artifacts will be provided in the
logs. Only people with access to our AWS account can see them.
