1426901 - Use react-codemod to remove deprecations/switch to JSX best practices

Status: RESOLVED INCOMPLETE

(Tree Management :: Treeherder: Frontend, enhancement, P3)

Description

[Ed Morley [:emorley]]

The react-codemod project has a number of jscodeshift transforms for converting deprecated code to newer patterns and performing best-practice cleanup:
https://github.com/reactjs/react-codemod

Whilst none of the transforms seem needed for our switch to React 16, there are still some of the best practices transforms (eg manual-bind-to-arrow, pure-component, ...) that will be worth running through.

Many of these have already been applied in other bugs.
