OK, this is ready for review now! (Obviously needs newer cosa to be rebuilt). |

This uses the new `cosa sign --oci` switch to sign our OCI images using the official Fedora GPG keys. Part of coreos/fedora-coreos-tracker#1969. I opted for not gating this behind a knob. It's safe to do this even on streams that still use encapsulated commits (it's just files in S3). But the earlier we do it, the more overlap we have in which both signature types (OCI and OSTree) co-exist and that makes migration planning easier.
