Stop Archiving Manifests
Stop Archiving Manifests

Archiving the tiny manifest files to glacier doesn't save anything since
they're so small and causes annoyances like when manifests.latest.yaml
gets pushed into Glacier and you have to wait for restores.

Hence changing config to only archive the larger artifact files and to
simply delete the old manifests when the old artifacts get deleted.
