have master create tunnels for all workers #780 (#1042)

## Description:
We want to move away from using nginx to cloudflare to route among
workers. This will simplify the nginx config, move routing computation
off the server, and make it easier to implement a multi-host
architecture.

The worker tunnels are not currently used.

I also moved the tunnel creation from startup.sh to Server. The shell
script was getting too complex.
