The name for this somehow seems wrong. It's not a helper for a plugin delegate.

Maybe something like RenderViewPepperHelper since from the render view's
perspective it's not a delegate, but the "thing that manages Pepper plugins for
the RenderView". Feel free to suggest a better name.

I agree RenderViewPepperHelper is a better name. I will rename this after all
comments are resolved.
