Plugin popup() api

Changes to JS API:
- popups have backdrop and is centered
- plugin.popup() takes a string custom element name
- plugin.popup() returns an API for closing and reopening the popup
- plugin.deprecated.popup() takes Element (similar to GWT Plugin JS API)

Recommended usage:

``` js
  Gerrit.install(function(plugin) {
    const popup = plugin.popup('my-plugin-popup-simple');;
    // ... work
    popup.close();
    // ... more work
    popup.open();
  });

```

``` html
<dom-module id="my-plugin-popup-simple">
  <template>
    <div>popup popup popup popup popup </div>
  </template>
  <script>
    Polymer({is: 'my-plugin-popup-simple'});
  </script>
</dom-module>
```
