Issue DM-4336: Global Metadata
Revisit design of the global metadata for LSST image and file archive. This includes understanding interactions between butler, local per repository metadata, global metadata, and metaserv. Sort out the dividing line between global metadata and dax (e.g., the schema https://github.com/lsst/dax_metaserv/tree/master/sql should live in cat/sql, not in dax) Deliverable: document describing the architecture of the global metadata, including how pipelines, users and SUI will interact with it. It should cover both writing/ingest and reading aspects.
