Major improvements to Synapse workers

This keeps the configuration cleaner and hopefully prevents odd issues
if Synapse (by any chance) happens to interpret `pusher_instances: []`
as "no pushers", instead of as "push from the master process".

I haven't confirmed what an empty pushers/federation-senders list means,
so it's safer to just avoid it.

.. although.. manual configuration is discouraged in most cases.
