ostree/summary: Generate an ostree-metadata ref when updating summary
This is the new way of publishing repository metadata, rather than as
additional-metadata in the summary file. The use of an ostree-metadata
ref means that the metadata from multiple upstream collections is not
conflated when doing P2P mirroring of many repositories.
The new ref is only generated if the repository has a collection ID set.
The old summary file continues to be generated for backwards
compatibility (and because it continues to be the canonical ref →
checksum map for the repository).
The new code is only used if configured with --enable-experimental-api.
Includes unit tests.
