Provide possibility to wrap components before render

[apsavin]

It's a feature request.
It would be great to have possibility to provide a wrapper component for all components in all tests.

Consider this example. I need App with context around all components that use css modules - literally all components that I want to test.

I can help with implementation, if you think the idea is ok.

This is a very good idea, and I would appreciate help implementing it. Starting point for that should be somewhere around client-wrapper.

This would help with things like adding fonts to the header.

This project is great. Best visual regression testing API ever.
