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 :)

This PR depends on #13172
Packager events are mostly logged through the TerminalReporter by default (#13172 makes this configurable). But there are a few things that aren't passed through TerminalReporter.
- We [log a banner with some information about the port and what's going on](8c7b32d5f1/local-cli/server/server.js (L22-L32))
- Also [a message about looking for JS files](8c7b32d5f1/local-cli/server/server.js (L34-L38)) (not sure what that is for / if it is useful beyond telling the user what directory root they started the packager in, but that's another thing).
- If the packager fails to start, then [we log an error message](8c7b32d5f1/local-cli/server/server.js (L41-L61)).

Summary:
In Expo tools such as XDE, exp we listen listen to stdout from the packager process and print it in our own buffer. In the case of XDE, an electron app, our log pane is DOM-based, and before printing each log chunk we need to remove special tty characters and sometimes parse it to get information that we need (eg: progress bar). By using a custom reporter, we can take the raw events and pass them along in a format that is easy to consume by XDE and exp. This same motivation applies to create-react-native-app, where we currently don't show a progress bar in the terminal, but we can with this change.

Summary:
Support symlinks under `node_modules` for all local-cli commands. PR https://github.com/facebook/react-native/pull/9009 only adds symlink support to the packager.
But other cli commands like `react-native bundle` creates its own instance of packager that doesn't have symlinks as part of its project roots, which results in the bundler breaking since it cannot find modules that you have symlinked.
This change ensures all `local-cli` commands add symlinks to its project roots.
Test plan (required)
1. Create a symlink in node_modules (for instance use npm/yarn link)
2. Run `react-native bundle`.

Summary:
If the packager is already watching `/path/to/MyProject`, and it finds symlinks inside `/path/to/MyProject/node_modules` that point to `/path/to/MyProject/path/to/somewhere/else`, there's no need to add the latter to the project roots.
**Test Plan:** replicate an aforementioned project set-up, and verify that only `/path/to/MyProject` is a project root for the packager, while files in `/path/to/MyProject/path/to/somewhere/else` can still be imported so long as they're part of an npm-style package (e.g. `/path/to/MyProject/path/to/somewhere/else/package.json` exists).

This will allow consumers to supply their own transformer to all `react-native` cli commands by simply implementing `rn-cli.config.js` and overriding `getTransformModulePath()`. That way they don't have to fork various parts of the iOS and Android build system that React Native already provides just to add a `--transformer` command line argument.

Summary:
This separates the babel config of the local-cli and the packager from the one used by the transforms of the packager since it doesn't run in the same environment and the local-cli/packager doesn't require react specific transforms and runs in node 4 so we can also avoid some es2015 transforms that node already supports.
I had to move the code in cli.js so it can still run in node 0.12 that doesn't support `const` since it is no longer transformed.
**Test plan**
Run the local-cli on node 0.12 and there should be a message saying that it requires at least node 4.
Run the local-cli on node 4 and 5 and everything should work the same as before.
I was also hoping for some perf gains but there was nothing noticeable. I did benchmark the babel-register call and it stayed pretty much the same. As for runtime performance it can help if there are optimisations for es2015 features in node.

And I think it's necessary to let user define host by cli argument.
It's also for security reason. When working on a public network, it's much safer to listen with localhost instead of ::, which may let everyone in same network be able to get your code from debugger-ui.

Summary:

We want to support Hot Loading on the packager itself instead of on the transformer. This will allow us to enable it on OSS (and for any scripting language, yay!).
For now to enable Hot Loading the packager's internals transforms need to be manually enabled (start packager with `--enable-internal-transforms`). I think the internal pipeline should always be enabled as it doesn't affect performance if there're no transforms and the user can disable Hot Loading through the setting on the app though. I'll tweak this on a follow up commit.

Summary:
public
This diff introduces an internal transforms pipeline that integrates with the external one. This has been a feature we've been looking to implement for a long time to use babel instead of `replace` with regexps on many parts of the packager.
Also, to split the bundle we'll need to run one transform. Internally for Facebook we can run the system-import transform altogether withe the other ones. For OSS we offer `transformer.js` which people can use out of the box if they're writing ES6 code. For those people, `transformer.js` will also run the internal transforms`. However they might want to tune the transforms, or even write the code on another language that compiles to Javascript and use a complete different transformer. On those cases we'll need to run the external transforms first and pipe the output through the internal transforms. Note that the order it's important as the internal transforms assume the code is written in JS, though the original code could be on other scripting languages (CoffeeScript, TypeScript, etc).
