For the Ember version `2.16`, they have removed the arguments passed to the `didReceiveAttrs` component lifecycle hooks. Previously I was getting arguments in the form of an object.

`newAttrs:`

```js
EmptyObject: 
{
  dataTestId: "test-object"
  items: MutableCell {__MUTABLE_CELL__       [id=__ember1555539649631463096066386]: true, __REF__ [id=__ember1555539649631670217952659]: RootPropertyReference, value: Array(27)}
  prompt: SafeString {string: "Select an Initiator Group"}
  required: true
  selected: MutableCell {__MUTABLE_CELL__ [id=__ember1555539649631463096066386]: true, __REF__ [id=__ember1555539649631670217952659]: RootPropertyReference, value: undefined}
  __proto__: Object
}
```

After deprecation how to get such an object in the `didReceiveAttrs`?
