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

Go through start.py when launching Synapse This allows us to benefit from helpful things it does for us, like enabling jemalloc: https://github.com/matrix-org/synapse/pull/8553 We weren't going through `start.py` before, because it was causing some conflict with our `docker run --user=...` stuff, but it doesn't seem to be a problem anymore. Having done this, we won't need to do things like https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/941 anymore.
