We need to migrate artifact object storage from S3 to GCS. This has the added benefit of allowing `direct_upload` of artifacts. Much of the work of this has already been done. We sync the GCS bucket with S3 daily so everything is kept up do date. The process for completing the migration should be as follows: - [ ] Disable `direct_upload` of artifacts - [ ] Run a final sync between S3 and GCS of the artifacts bucket - [ ] Change storage location in `gitlab.rb` to point to GCS - [ ] Verify artifacts still work - [ ] Enable `direct_upload` of artifacts once more - [ ] migrate the artifacts that landed on disk to object storage cc/ @ayufan @jarv @dosuken123
