[React] PropTypes and PropTypes shapes

[furdzik]

• How to create shapes, put it in component folder? And what if components share one or more shapes? Use centerline convention?
• Consistent naming convention for shapes names (e.g. name in shapes folder in utils or if I will decide to go with this direction in component folder)

[CONSIDER]

1. One name of main folder with shapes: now is types, or shapes is better
2. Two names, if using TypeScript use types, if using PropTypes use shapes
