Added a vanilla React Native example app.

[tmeasday]

Issue: We need an example app for RN! #1012

What I did

cd examples
react-native init ReactNativeVanilla
cd ReactNativeVanilla
# --> checked it ran normally

getstorybook
# --> checked it ran -- actually there was an issue #1200 I worked around

# --> updated package.json w/ file:// ref to @storybook/react-native
npm install
# --> checked it ran -- I had to revert to RN 0.44.1 because of https://github.com/facebook/react-native/issues/14209]

# --> updated package.json w/ file:// ref to @storybook/addon-storyshots
npm install
# --> added `__tests__/storyshots.js` test file
npm test # <- ensured it worked as expected.

# --> updated package.json w/ file:// ref to @storybook/addon-options
# --> Added code to use options in `storybook/addons.js` and `storybook/index.ios.js` 
#    (note had to work around https://github.com/storybooks/storybook/issues/1192 with a `setTimeout`)
npm run storybook / react-native run-ios # <-- to check the options worked.

How to test

1. Checkout, npm install.
2. Run the storybook via (a) npm run storybook + react-native run-ios. Check the stories are displayed and the name option works.
3. Run npm test, ensure 3 snapshots are recorded.

Thanks CodeFactor! I tried to work around https://www.codefactor.io/repository/github/storybooks/storybook/pull/1202 but could not :)

Please give me a chance to review before merging 😸

@shilman see in this description why I didn't just import a common file: #1201

[shilman]

@tmeasday you need to add this to lerna.json to ignore for both publish and bootstrap. We don't want to publish it. For bootstrap, it fails if I run a clean bootstrap from the root. But if I go to the RN app directory and npm install it works.

Should we keep all folder-names lowercase and dash separated ?

[tmeasday]

React Native wouldn't let me pass such a name into it. I'm scared to change it after the fact ;) [I'll try]

[tmeasday]

Ok, made the changes requested
