docker connection from local

[okdistribute]

there's something @maxogden and @joehand figured out for try-dat.com that we also should apply here for the docker container.

[joehand]

switched to host networking mode, now that all the ports are shared amongst all processed, lots of bugs creeped up because 2 containers would try to listen on the same port

[joehand]

We are using https://github.com/jwilder/nginx-proxy for the networking mode, so we need to figure out how to get that to work with dat or something. =(

Tried these things:

• Exposed & opened 3282 & 3282/udp in the docker run command
• Turned on udp in dat-registry-api

I got one connection that was hole-punched to my local but not working anymore, so not really sure what is going on.
