* Persist partition|offset|user_id in the keyserver Required for a query API which will be used by the syncapi which will be called when a `/sync` request comes in which will return a list of user IDs of people who have changed their device keys between two tokens. * Add tests and fix maxOffset bug * s/offset/log_offset/g because 'offset' is a reserved word in postgres
