Add FederationClient interface to federationsender (#1284)
* Add FederationClient interface to federationsender

- Use a shim struct in HTTP mode to keep the same API as `FederationClient`.
- Use `federationsender` instead of `FederationClient` in `keyserver`.

* Pointers not values

* Review comments

* Fix unit tests

* Rejig backoff

* Unbreak test

* Remove debug logs

Key Server

This is an internal component which manages E2E keys from clients. It handles all the Key Management APIs with the exception of /keys/changes which is handled by Sync API. This component is designed to shard by user ID.

Keys are uploaded and stored in this component, and key changes are emitted to a Kafka topic for downstream components such as Sync API.

Internal APIs

  • PerformUploadKeys stores identity keys and one-time public keys for given user(s).
  • PerformClaimKeys acquires one-time public keys for given user(s). This may involve outbound federation calls.
  • QueryKeys returns identity keys for given user(s). This may involve outbound federation calls. This component may then cache federated identity keys to avoid repeatedly hitting remote servers.
  • A topic which emits identity keys every time there is a change (addition or deletion).

### Endpoint mappings

  • Client API maps /keys/upload to PerformUploadKeys.
  • Client API maps /keys/query to QueryKeys.
  • Client API maps /keys/claim to PerformClaimKeys.
  • Federation API maps /user/keys/query to QueryKeys.
  • Federation API maps /user/keys/claim to PerformClaimKeys.
  • Sync API maps /keys/changes to consuming from the Kafka topic.
