Support cloud endpoints in local dev environment about google-apis HOT 5 CLOSED

So I've been thinking that we could add the following attributes to allow most flexibility while keeping the defaults simple:

local / boolean / default false
localHost / string / default 'localhost'
localPort/ int / default 8080

With local set, http://{{localHost}}:{{localPort}}/_ah/api would be used with the defaults used as in the app engine default configuration. The appId parameter would be ignored in this case.
Default values could be overwritten using localHost and localPort, e.g. if you are running your dev server on a different machine.

In the simplest case you would then have
Dev env: <google-api-loader api="myApi" version="v1" local></google-api-loader>
Deployed: <google-api-loader api="myApi" version="v1" appId="myAppId"></google-api-loader>

Developers could also use a conditional attribute for local, to simply switch between dev and deployed environment, but that's up to them how to implement this:
<google-api-loader api="myApi" version="v1" appId="myAppId" local?="{{dev}}"></google-api-loader>

@ebidel, thoughts? I could PR those changes if they sound okay to you.

I think we need a new element for the cloud stuff for two reasons:

1. these additional params won't make sense for the majority of the API
2. we should exercise the extensibility and reusability of components :)

` (or something similar).

For the specific param name, I like what the app engine dev_server does with --host and --port. We could do:

<google-cloud-endpoints-api appId="myAppId" host="localhost" port="8080"></google-cloud-endpoints-api>

If host or port are given, they override appId to form the URL.

An alternative (but more work) would be to create a mock element for testing. Scott through this POC together for core-ajax: https://github.com/PolymerLabs/mock-ajax

from google-apis.

mock-ajax sounds great but I think it has a different purpose. You'd still want to be able to load a custom API from dev server to run a local copy of the app, as well as maybe run automated tests with mock-ajax. But it's different, unless I'm missing something.

Why not just change appId attribute to root? That way the loader would support both dev and production/deployed:

Dev:
<google-api-loader name="myApi" version="v1" root="http://localhost:8080/_ah/api">

Prod:
<google-api-loader name="myApi" version="v1" root="https://myapp.appspot.com/_ah/api">

statuses_[this.name] = 'loading';
loaders_[this.name] = this;
gapi.client.load(this.name, this.version, 
    this.handleLoadResponse.bind(this), this.root);

Can't use this element with polymer starter kit and local development endpont cause new root property overlaps with some #document-fragment and can't be set. I think it should be renamed to somethong other than root, apiroot for example.

Hah, I just encountered a similar problem and created a new issue here: #49
