Add initial support for synapse workers · needs documentation; no checks yet for port clashes or typos in worker name · according to https://github.com/matrix-org/synapse/wiki/Workers-setup-with-nginx#results about 90% of requests go to the synchrotron endpoint · thus, the synchrotron worker is especially suited to be load-balanced · most of the other workers are documented to support only a single instance · https://github.com/matrix-org/synapse/blob/master/docs/workers.md 2020-04-10 21:44:53 +00:00			`---`

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			`# A previous version of the worker setup used this.`
