As a user, zchunk metadata is supported
Ticket moved to GitHub: "pulp/pulp_rpm/2212":https://github.com/pulp/pulp_rpm/issues/2212
In Fedora 30, Zchunk metadata is going to be present alongside with older compression formats.
Pulp3 should handle this type of metadata.
Ideally, it should be ignored during sync and optionally generated during publish (similar to sqlite dbs).
