* Server key API (works for monolith but not for polylith yet) * Re-enable caching on server key API component * Groundwork for HTTP APIs for server key API * Hopefully implement HTTP for server key API * Simplify public key request marshalling from map keys * Update gomatrixserverlib * go mod tidy * Common -> internal * remove keyring.go * Update Docker Hub for server key API * YAML is funny about indentation * Wire in new server key API into hybrid monolith mode * Create maps * Route server key API endpoints on internal API mux * Fix server key API URLs * Add fetcher behaviour into server key API implementation * Return error if we failed to fetch some keys * Return results anyway * Move things about a bit * Remove unused code * Fix comments, don't use federation sender URL in polylith mode * Add server_key_api to sample config * Review comments * HTTP API to cache keys that have been requested * Overwrite server_key_api listen in monolith hybrid mode
