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.

There are several npm packages that are no longer used and do not show up when grepping the code base. Also the "async" dependency is used only in CI and should be moved to devDependencies.

Summary:
Adding a Babel plugin that will analyze the file looking for any potential candidate to use `regenerator-runtime`, and if so, will inject dynamically the module. The module is injected per file, so we avoid polluting the global environment. The plugin is also able to inject the `require` call beforehand, so that the inliner can pick them and inline them.
The Babel plugin is part of `react-native-babel-preset`, so as long as you are using this preset you are safe. If not, you should include the specific transformer into your list of plugins, as `react-native-babel-preset/transforms/transform-regenerator-runtime-insertion.js`.

Summary:
Many issues filed on Github are missing platform/toolchain version information. Others have different ways of writing it, and require the issue writer to look in multiple places for these versions.
Other CLI tools like Ionic have this function, and it's incredibly useful. Related to https://github.com/facebook/react-native/issues/14420

Summary: Move the returned type of `getPolyfills` from a standard `Array` to a read-only one, so that we make sure the array is not modified once created. Also, refactor the list of polyfills included by default to a generic, central file, then require it both from the CLI utils as well as the development server.

Summary:
There were still some references to "packager/" that are no longer used since the `packager` directory has been deleted after moving to Metro. Cleaned up the ones that were doing nothing and updated the references that are still meaningful.

Summary:
This diff cleans up some cruft and adds some features:
* It removes the usage of an env variable to control workers.
* It removes the lazy and handwavy calculation on how many workers to use for jest-haste-map. Jest itself uses the maximum amount of workers available and it has never been reported as an issue – especially since it is a one-time startup cost of about 3 seconds on a cold cache only.
* It adds a `--max-workers` flag to replace the env variable. This one is able to control both the number of workers for `jest-haste-map` as well as the transformers.
* It makes the transformers run in the parent process if 1 or fewer workers are are specified. This should help with debugging.
Once you approve this diff, I will publish a new version of metro to npm and update the version used in RN and remove the use of the env variable altogether: https://our.intern.facebook.com/intern/biggrep/?corpus=xplat&filename=&case=false&view=default&extre=&s=REACT_NATIVE_MAX_WORKERS&engine=apr_strmatch&context=false&filter[uninteresting]=false&filter[intern]=false&filter[test]=false&grep_regex=
Note: the process of adding a CLI option is really broken. Commander also has a weird API. We should consider building a better public API for Metro and then consider how to build a new CLI on top of it and simplify our internal integration. I really don't like how Metro is integrated across pieces of the RN cli in ways that is hard to manage. But that is a larger task for another time :)
