Summary:
We use a custom rn-cli.config.js file that specifies a custom blacklist. In addition to blacklisting some of our own directories, we still want to keep RN's default rules for what to blacklist so we also call into the packager's blacklist.

Summary: The `DependencyGraph-test` hangs forever if run in isolation because the watch mode is not properly ended. I propose we just wrap each test in a function that does the correct thing, and also migrate tests to `async`/`await`.

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 :)

Summary: I wanted to settle #18056064 once and for all. This solution both uses (1) random generation of temp dir, and (2) minimal overhead in the repo. The reason random generation of temporary folder directory names should always be used is the same as why [`mktemp(3)` should never be used](http://man7.org/linux/man-pages/man3/mktemp.3.html#BUGS). The reason we don't want the cache to be fully stored locally (2) is because watchman would catch too many change events we don't care about, hitting performance. Additionally, (1) has the benefit that when one clones the repo from fresh, it'll also always start with a fresh cache. (1) uses a function equivalent to [`mkdtemp(3)`](http://man7.org/linux/man-pages/man3/mkdtemp.3.html), that we cannot use here because it's POSIX and not exposed by the Node.js API.

Summary:
The 'fs' mock was set up to require 'graceful-fs', which used to delegate to the corresponding mock. After turning off automocking, this no longer necessarily works.
This moves the mock to `fs.js` and makes the mock for graceful-fs require the fs mock via a relative path.

Summary:
The packager dependencies CLI command always operates on --dev=true today. This means any tooling that needs to get the production dependencies (--dev=false) will always get the dev-mode list instead. For instance:
```
if (__DEV__) {
require('Foobar');
}
```
Previously, `Foobar.js` will always be listed in the CLI output. With this change, setting `--dev false` option will correctly skip `Foobar.js` in the output.
