Adds a schematic and tslint rule that automatically migrate the consumer from `Renderer` to `Renderer2`. Supports:
* Renaming imports.
* Renaming property and method argument types.
* Casting to `Renderer`.
* Mapping all of the methods from the `Renderer` to `Renderer2`.
Note that some of the `Renderer` methods don't map cleanly between renderers. In these cases the migration adds a helper function at the bottom of the file which ensures that we generate valid code with the same return value as before. E.g. here's what the migration for `createText` looks like.
Before:
```
class SomeComponent {
createAndAddText() {
const node = this._renderer.createText(this._element.nativeElement, 'hello');
node.textContent += ' world';
}
}
```
After:
```
class SomeComponent {
createAndAddText() {
const node = __rendererCreateTextHelper(this._renderer, this._element.nativeElement, 'hello');
node.textContent += ' world';
}
}
function __rendererCreateTextHelper(renderer: any, parent: any, value: any) {
const node = renderer.createText(value);
if (parent) {
renderer.appendChild(parent, node);
}
return node;
}
```
