This PR:

• Adds VictoryBrushContainer
• Adds VictoryZoomContainer
• Deprecates VictoryZoom
• Changes default styles for VictorySelectionContainer
• Adds override-able selectionComponent for VictorySelectionContainer
• Adds domain and standalone to list of props that get stored in parent state
• Simplifies and standardizes container rendering across components.

Here's an example using VictoryZoomContainer and VictoryBrushContainer:

class App extends React.Component {
  handleZoom(domain) {
    this.setState({selectedDomain: domain});
  }

  handleBrush(domain) {
    this.setState({zoomDomain: domain});
  }

  render() {
    return (
      <div>
        <VictoryChart width={800} height={500} scale={{x: "time"}}
          containerComponent={
            <VictoryZoomContainer responsive={false}
              zoomDomain={this.state.zoomDomain}
              onDomainChange={this.handleZoom.bind(this)}
            />
          }
