Consistency between http.getAgent and https.getAgent

[indexzero]

Working on adding HTTPS support to node-http-proxy and I've come across an inconsistency in the https vs. http APIs. The correct usage for "getAgent" on the respective modules are:

https.getAgent({
  host: 'localhost',
  port: 8080
});

http.getAgent('localhost', 8080);

Wanted to get input before I whip up a patch one way or the other.
