Bump max params to 5

@malandrew @Raynos

This is a proposal to bump max-params to 5.

The tchannel handler functions take 5 parameters:

module.exports = function doSomething(options, req, head, body, callback) {
};

Disabling this for every handler is a pain. If we're all moving towards tchannel, it seems like a good reason to bump this to 5.

@malandrew Can you merge and cut a new version when you're ready?
