Issue: Document relationship between AutomaticKeepAliveClientMixin and addAutomaticKeepAlives
Labels: framework,d: api docs,P2,team-framework,triaged-framework

## Steps to Reproduce

1. Create an app that contains a list view, and add StatefulWidgets as children for this list view. For example:

```dart
import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      home: Scaffold(
        body: ListView(
          children: List.generate(50, (index) => MyStatefulWidget(index)),
        ),
      ),
    );
  }
}

class MyStatefulWidget extends StatefulWidget {

  final int index;

  MyStatefulWidget(this.index);

  @override
  _MyStatefulWidgetState createState() => _MyStatefulWidgetState();
}

class _MyStatefulWidgetState extends State<MyStatefulWidget> {

  @override
  void initState() {
    print('initState called for ${widget.index}');
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return ListTile(
      title: Text('hello ${widget.index}'),
    );
  }
}
```
2. Start the app, and scroll down, you will see "initState called for ... " for more and more indices as you scroll down, which is the normal behaviour.
3. Then, scroll up, you will see initState called for ... " for entries where initState has already been called.

This causes a problem, because we might be doing some expensive operations in initState. This has also caused me significant problems where the StatefulWidget was actually a FutureBuilder
