add babel esm and umd exports

[redallen]

Fix openshift/console#2232 upstream.

should NODE_ENV=production and && shx rm -rf dist be preserved?

[redallen]

NODE_ENV=production doesn't matter. I added back the prebuild step, though.

cc: @suomiy @mareklibra - it seems you'll need to export ESM to treeshake Console UI bundle. Thanks @redallen !

also, the tests are failing with

babel-jest: Babel ignores src/jest/setupTest.js - make sure to include the file in Jest's transformIgnorePatterns as well

@suomiy I fixed the tests and addressed your feedback. We needed a CJS babel config for Jest to run the tests on Node, so I passed it manually to Jest.

CreateVMWizard.test.js seems to have something weird going on with it:

console.error node_modules/react/cjs/react.development.js:225
Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Check the render method of `WizardPatternBody`.
    in WizardPatternBody (created by WizardPattern)
    in div (created by ModalBody)
    in ModalBody (created by WizardBody)
    in WizardBody (created by WizardPattern)
    in div (created by Wizard)

but I think that's outside the scope of this PR and is probably a PatternFly problem.

We should remove the dependency cycles in a follow-up.
Brief look - this should not be so difficult.

@mareklibra Added the ignores.

Thank you for the patch!
