Before this change: * `PerspectivesKeyFetcher` and `ServerKeyFetcher` write to `server_keys_json`. * `PerspectivesKeyFetcher` also writes to `server_signature_keys`. * `StoreKeyFetcher` reads from `server_signature_keys`. After this change: * `PerspectivesKeyFetcher` and `ServerKeyFetcher` write to `server_keys_json`. * `PerspectivesKeyFetcher` also writes to `server_signature_keys`. * `StoreKeyFetcher` reads from `server_keys_json`. This results in `StoreKeyFetcher` now using the results from `ServerKeyFetcher` in addition to those from `PerspectivesKeyFetcher`, i.e. keys which are directly fetched from a server will now be pulled from the database instead of refetched. An additional minor change is included to avoid creating a `PerspectivesKeyFetcher` (and checking it) if no `trusted_key_servers` are configured. The overall impact of this should be better usage of cached results: * If a server has no trusted key servers configured then it should reduce how often keys are fetched. * if a server's trusted key server does not have a requested server's keys cached then it should reduce how often keys are directly fetched.
