Add a command line parameter to specify IP to listen on for HTTP.

[TJ09]

Right now, the HTTP module only accepts a port as configuration. In a machine with multiple IPs/interfaces, there is no way to set which interface is used (e.g. a system with an external and LAN IP has no way to force a service to listen only on the LAN IP and not all interfaces). It'd be nice to have --http_ip or something to control this behavior.

@TJ09 Do you have a workaround for this issue?

Does --http_host not work for some reason?

On second thought I assume this is an issue with the Java library?

[StephanErb]

If I understand TJ09s intention correctly, this ticket was meant to be a prerequisite for https://issues.apache.org/jira/browse/AURORA-572. However, looking at the code this might not actually be true.

[TJ09]

That was the intention, specifically because I was directed (in #aurora on Freenode) to file tickets in both Twitter Commons and Aurora for solving the same overall problem.

And yes, this is a Java issue, rather than python. Sorry, I didn't realize that there were multiple languages in one repo.
