refactor(drawing/DrawingManager): rewrite with enhanceElement and cle…

…aner interfaces

BREAKING CHANGE: Naming convention for event handlers has tweaked to follow React's convention.

Before:

```js
<DrawingManager
  onCirclecomplete={_.noop}
  onOverlaycomplete={_.noop}
/>
```

After:

```js
<DrawingManager
  onCircleComplete={_.noop}
  onOverlayComplete={_.noop}
/>
```
