* Initial federation sender -> federation API refactoring * Move base into own package, avoids import cycle * Fix build errors * Fix tests * Add signing key server tables * Try to fold signing key server into federation API * Fix dendritejs builds * Update embedded interfaces * Fix panic, fix lint error * Update configs, docker * Rename some things * Reuse same keyring on the implementing side * Fix federation tests, `NewBaseDendrite` can accept freeform options * Fix build * Update create_db, configs * Name tables back * Don't rename federationsender consumer for now
