Skip the actual S3 uploads and modify GitHub reporting on GitLab CI
Skip the actual S3 uploads and modify GitHub reporting on GitLab CI

The idea is to not interfere in the current develop process while we run
the trial period on GitLab CI. For GitLab, S3 uploads are skiped, and
the GitHub PR reports are modified so that can live side-by-side with
the Jenkins ones.

Changelog: None
