@mhevery Can you approve the public API changes? Reviewed informally with Igor before he left, but I need the formal PR approval for the check. |

This commit introduces a new Input property called
`ngFormOptions` to the `NgForm` directive. You can use it
to set default `updateOn` values for all the form's child
controls. This default will be used unless the child has
already explicitly set its own `updateOn` value in
`ngModelOptions`.
Potential values: `change` | `blur` | `submit`
```html
<form [ngFormOptions]="{updateOn: blur}">
<input name="one" ngModel> <!-- will update on blur-->
</form>
```
For more context, see [angular#18577](angular#18577).
