Create release as a pre-release, upload all files, then change to published release

[drnic]

The moment that a release is created (non pre-release) then any other concourse pipeline that watches it can trigger - except that the release might not yet be finished. If the finished release includes several large files, then it is possible for downstream pipelines to trigger too early.

Perhaps if we create the release as a pre-release, then upload files, then switch to a final release we will have happy downstream pipelines?
