Clear up makeRequest_ naming conventions

[stephenplusplus]

We follow a few different patterns throughout the codebase, so I think we should try to sync up.

In some constructors, you might find this.makeRequest_ = storage.bucket.makeRequest.bind(storage.bucket). In other places, we define a makeRequest_ on the prototype. (props to @callmehiphop for first calling us out on this).

We should also clear up the naming conventions around making requests. Currently:

function Class() {
  this.makeAuthorizedRequest_ = util.makeAuthenticatedRequestFactory();
}

Class.prototype.makeReq_ = function(method, path, qs, body, callback) {
  var reqOpts = {
    method: method,
    uri: path,
    // ...
  };

  this.makeAuthorizedRequest_(reqOpts);
};

I think we should go through and have only one style; Class.prototype.request instead of constructor-initialized functions.

function Class() {
  this.authClient = util.getAuthClient();
}

Class.prototype.request = function(reqOpts, callback) {
  util.request(this.authClient, reqOpts, callback);
};

It should make it easier to follow along with, and it should be possible.

Also note using (reqOpts, callback) over (method, path, query, body, callback). It's pretty non-JS to have multiple arguments. We should just use the standard request options format, with reqOpts.uri, reqOpts.method, reqOpts.qs, reqOpts.json, etc.

LMKWYT!
