add custom devDep pattern for import/no-extraneous-dependencies

[gavinsharp]

import/no-extraneous-dependencies is an ESLint rule that is intended to ensure that you don't import libraries installed as devDependencies from inside non-dev code. It needs to be configured with glob patterns to let it know which files should be considered "dev-only".

Several of our projects have had to set up custom overrides of the this rule because the default config (configured in eslint-config-airbnb-base) was not aware of these dev-only files. This is an attempt to centralize those exceptions so that each project doesn't have to roll their own. Specifically, I am adding:

• '.storybook/**' and 'stories/**' (Storybook files used in Linoleum)
• **/setupTests.js (Create React App test setup file, used in web apps)
• **/*.config.js (misc. config files used throughout our apps, including Webpack, Rollup, Babel, ESLint, postcss, etc.)

Since we are overriding the rule definition from eslint-config-airbnb-base, I also needed to copy the test file patterns we use from their rule set.
