Run Synapse workers in their own containers This switches the `docker exec` method of spawning Synapse workers inside the `matrix-synapse` container with dedicated containers for each worker. We also have dedicated systemd services for each worker, so this are now: - more consistent with everything else (we don't use systemd instantiated services anywhere) - we don't need the "parse systemd instance name into worker name + port" part - we don't need to keep track of PIDs manually - we don't need jq (less depenendencies) - workers dying would be restarted by systemd correctly, like any other service - `docker ps` shows each worker separately and we can observe resource usage 2021-01-25 10:14:46 +00:00
