Support for InputLabelProps

[volodymyrpavliuk]

As one can see, currently only a limited set of prop names are passed into underlying TextField component.

It is quite often required to manage Input label props, e.g. provide custom styles via classes, or add custom shrinking behavior

Is it possible to include InputLabelProps prop to a list of allowed props so that above could be achieved?

Thanks
