Add route based lookup API

[ritch]

This would make it easier for us to support configurations that take an API or route as input instead of an exact SharedMethod name. Below are some basic examples

var methods = remotes.findByRoute('get', '/todos');
console.log(methods[0].name); // => find

// glob supported
var methods = remotes.findByRoute('get', '**');
// => all GET methods

var methods = remotes.findByRoute('get', '/*/*/count');
// => all count methods
