Summary:
`metro-bundler` v0.21 contains a rewritten bundling mechanism, with simplified logic and much faster rebuild times, called delta bundler. This release contains a couple of breaking changes:
* Now, when using a custom transformer, the list of additional babel plugins to apply are passed to the `transform()` method. These are used in non-dev mode for optimization purposes (Check 367a5f5db8 (diff-40653f0c822ac59a5af13d5b4ab31d84) to see how to handle them from the transformer).
* Now, when using a custom transformer outputting `rawMappings`, the transformer does not need to call the `compactMappings` method before returning (check d74685fd1d (diff-40653f0c822ac59a5af13d5b4ab31d84) for more info).
* We've removed support for two config parameters: `postProcessModules` and `postProcessBundleSourcemap`.

Summary:
Prettier 1.7.0 has config file + pragma support so this works really well with the current prettier usage. Also added a prettier script to run it (taken mostly from the relay repo) and ran it which caused 1 files to change (probably wasn't updated when upgrading prettier to 1.7.0).
**Test plan**
Made sure flow still checked
Run 'yarn prettier', should format only files with `format` using the config in package.json.

Summary:
Adds the dependency to the Babel preset's package.json and enables the plugin only when `**` exists in a source file.
This is https://github.com/facebook/react-native/pull/12339 with merge conflicts resolved and putting the plugin behind a cheaper heuristic.

Summary:
This is first PR from the series I am going to be sending as a result of fixing 0.50-stable test suite. This one removes `mockFS` dependency that has been causing failures on Node 6.x container.
Here's build before this change: https://circleci.com/gh/facebook/react-native/22529
Here's build after this change: https://circleci.com/gh/facebook/react-native/22538 (green)
Note that the CI may be still red as there are other PRs to be addressed. You can see this in the wild on 0.50.

Summary:
This change only affects tests run with Jest. `require('/images/image1.png')` will be replaced with
```
Object {
"testUri": "relative/path/to/images/image1.png",
}
```
in the Jest snapshot instead of always being 1 returned by RelativeImageStub. This change makes it possible to test conditional asset loading in components.
The problem with this change is that it will probably break a lot of existing snapshots, but that should be easily fixed when a project updates to a new version of React Native by running `jest -u` to update all snapshots.
A component can have conditional asset loading based on its props, this logic would be nice to test with Jest snapshots. This problem has been discussed in https://github.com/facebook/jest/issues/2838.
* **Who does this affect**: Everyone using `Image` in Jest snapshots
* **How to migrate**: Running `jest -u` will update the snapshots, the snapshots should be reviewed that they are correct.
* **Why make this breaking change**: It enables testing of conditional asset loading.
* **Severity (number of people affected x effort)**: Low.
