Document the database schema

[andrew]

Would be very handy to have a list of the key formats and expected values in leveldb so you don't have to search through the code to find how/where to retrieve some data from.

Some keys off the top of my head:

• pkg:${manager}:${name} - metadata (json for npm or string for go)
• cid:${manager}:${name}:${version} - cid string
• size:${manager}:${name}:${version} - int (bytes)
• mod:go:${name}:${version} - go.mod contents (string)
• info:go:${name}:${version} - go metadata (json)
• latest:go:${name} - go latest version (json)
• repub:${manager}:${name}:${version}:${peerid} - timestamp
