**Do you want to request a *feature* or report a *bug*?**

feature: add support for the [nomodule](https://hospodarets.com/native-ecmascript-modules-nomodule) attribute to the script tag. 

**What is the current behavior?**

with `<script nomodule src="foo.js" />` i get:
```
Warning: Received `true` for a non-boolean attribute `nomodule`.
If you want to write it to the DOM, pass a string instead: nomodule="true" or nomodule={value.toString()}.
```
and the attribute is removed. 

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar (template for React 16: https://jsfiddle.net/Luktwrdm/, template for React 15: https://jsfiddle.net/hmbg7e9w/).**

https://jsfiddle.net/hzdkwne6/

**What is the expected behavior?**

the `nomodule` attribute should be respected

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

react 16.2.0
chrome
osx

not a regression, i don't think it's ever worked before.

if this isn't an intentional oversight i'll open a pr to add it, seems like it's just a change to https://github.com/facebook/react/blob/master/fixtures/attribute-behavior/src/attributes.js ?
