Add hole punch forwarding to master server.
...
If a server is behind a NAT gateway or firewall its UDP port may be
accessible to the master server but not to other clients. For some types
of gateway we can work around this by having the servers explicitly send
a packet to the client that is trying to connect to them ("hole punching").
The master server can serve as a trampoline to forward this request from
clients.
This is the initial master server-side part of implementing
chocolate-doom/chocolate-doom#469 .

This reduces the metadata response size slightly as we no longer need
to return a number of decimal points.
