[DISCUSS] Master redirection with EC2

[Brenden Matthews]

Folks,

I'd like to be able to make the master redirection in the web UI work with
EC2, which has weird internal/external IP address issues.

I was thinking about adding a hostname to the Master info message, and
adding that along with the libprocess PID into the ZooKeeper state in
detector.{cpp,hpp}.

Any thoughts on this?  Are there any objections or concerns?  From
examining the code, I couldn't think of a better way to do this.

Thanks!

Brenden
