Add NATS JetStream support (#1866) * Add NATS JetStream support Update shopify/sarama * Fix addresses * Don't change Addresses in Defaults * Update saramajetstream * Add missing error check Keep typing events for at least one minute * Use all configured NATS addresses * Update saramajetstream * Try setting up with NATS * Make sure NATS uses own persistent directory (TODO: make this configurable) * Update go.mod/go.sum * Jetstream package * Various other refactoring * Build fixes * Config tweaks, make random jetstream storage path for CI * Disable interest policies * Try to sane default on jetstream base path * Try to use in-memory for CI * Restore storage/retention * Update nats.go dependency * Adapt changes to config * Remove unneeded TopicFor * Dep update * Revert "Remove unneeded TopicFor" This reverts commit f5a4e4a339b6f94ec215778dca22204adaa893d1. * Revert changes made to streams * Fix build problems * Update nats-server * Update go.mod/go.sum * Roomserver input

into correct JetStream subject * Async and sync roomserver input * Update dendrite-config.yaml * Remove roomserver tests for now (they need rewriting) * Remove roomserver test again (was merged back in) * Update documentation * Docker updates * More Docker updates * Update Docker readme again * Fix lint issues * Send final event in `processEvent` synchronously (since this might stop Sytest from being so upset) * Don't report event rejection errors via `/send`, since apparently this is upsetting tests that don't expect that * Go 1.16 instead of Go 1.13 for upgrade tests and Complement * Revert "Don't report event rejection errors via `/send`, since apparently this is upsetting tests that don't expect that" This reverts commit 368675283fc44501f227639811bdb16dd5deef8c. * Don't report
