This is a follow-up to famedly/local#33, where the appservice
registration file was unreadable. This also enables all workers
to be able to read the file, which is required.
Can deploy synapse workers and allow costum amounts of workers for each
type. For documentation on how to use, see `roles/synapse/README.md`.
In a docker deployment, each worker runs in their own docker container
with respective listener configurations. Labels can be declared in
`tasks/configure_workers.yml` for routing of requests.
In systemd deployments, each worker runs in it's own systemd service,
which are marked as being part of the main service, so restarting the
main service will restart all the workers as well.
