Problem

Something is needed by crates.io for creating index entries, rather than reading the json blob which might be out of sync. They switched to community developed crates but this creates hidden relationships when making manifest changes (rust-lang/crates.io#6914).

Proposed Solution

Bigger requests, like #4614, are blocked on the fact that the code ties into everything within cargo. So instead, let's get an incremental step by just putting out the schemas, with no business logic.
