Document using tmpnb against a swarm cluster

[rgbkrk]

Two modes:

• tmpnb + the proxy run on a separate node, while reaching out to a swarm cluster (1 -> many)
• run tmpnb on a swarm node, launching with the local docker daemon (1 -> 1)

Part of this is in https://github.com/jupyter/tmpnb/pull/154, working on a real document now.

For the second mode, do you need to do anything differently from how you would normalle start tmpnb?

[rgbkrk]

tmpnb needs to be able to access the certs and have the docker configuration passed in (with the same environment variables you come to expect with docker machine).

So are there any docs on how to run tmpnb against a swarm?
