Summary:
We have found that it is useful to work with production rather than dev bundles when working on e.g. performance and animation tuning.
For a larger app, `react-native bundle` with `--dev false` can get very slow due to minification - in our case, this was especially true of library code (e.g. the AWS SDK taking nearly 15 secs to minify on a top-spec MBP 15"). This is fine when just building every now and then, but when making frequent changes and rebuilding, it becomes quite painful.
Currently there is no way to perform a release (non-dev) build, with minification disabled. This PR adds an optional `--minify` flag to enable developers to disable minification, reducing build times significantly for our use case.
Checked output bundle size, to ensure behaviour stays the same as the existing default when `--minify` is not specified, and that the `minify` flag gets passed through to Metro bundler correctly if specified.

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:
This is an initial step of rewriting the CLI interface to use `rnpm` one (commander, plugins etc.).
It's scope is to move all existing commands to use rnpm CLI interface, so that we get plugins, flags and our existing ecosystem working out of the box.
<s>This is still WIP and some of the commands are left commented out.</s>
For the `config` of `rnpm` (functions get info about project and dependency), <s>I am thinking we can merge them with</s> we decided to merge it with [`default.config.js`](e57683e420/local-cli/default.config.js (L33)), so they are available on the `new Config()` [instance](e57683e420/local-cli/cliEntry.js (L59)) (which means we don't have to change anything and current plugins, like runIOS and runAndroid can just start using it [w/o depending on any extra argument](https://github.com/grabbou/react-native/blob/e57683e420210749a5a6b802b4e

Summary:
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.
**Test plan:** Applied this patch to the React Native version in my app, implemented `getTransformModulePath()` in my `rn-cli.config.js`, and verified that my custom transformer is invoked.

Summary:
`react-native start` already ensures that the `--transformer` path is understood to be relative to CWD, not to the module that ends up importing that file. `react-native bundle` and `react-native dependencies` didn't up until this point.
**Test plan:** Ensured that `react-native bundle ... --transformer ./relative/path` works with this patch applied.

Summary:
Currently the `react-native bundle` has no option to reset the file cache. For example changing the .babelrc has no effect on the bundling process. `react-native start` has it already implemented, so this is just a small addition.
**Test plan (required)**
the issue:
- `react-native init` a new project
- run `react-native bundle` (should work as expected)
- create `.babelrc` with empty object ```{}```
- rerun `react-native bundle`
- should fail now with `Unexptected token` (no babel plugins configured)
- if not failing, your cache already hit (clear $TMPDIR to get the error)
- delete .babelrc and rerun `bundle`
- still failing, but it should went back to normal
- delete your $TMPDIR contents
- works again
The option `--reset-cache` should fix that

Summary: This adds a build option for using Prepack (an experimental packager) to
build a bundle. It doesn't actually take on the npm package dependency
because it's not published/open source (yet).
This will be used while we experiment and should be maintained as the
build system changes so that we can continue getting fresh builds.
I found that saveBundleAndMap and processBundle were over abstracted and
got in my way so I inlined it and removed the unit tests because the unit
test was testing trivial code that is likely to change interface.
I went with a separate build phase and a separate Bundle class even though
there are a lot of commonalities. I imagine that the requirements for
Prepack will continue to diverge. Especially for source maps but a larger
refactor could try to unify these a bit more. The fact that modules are
wrapped before the write phase seems to be an unfortunate architecture
that makes this difficult.

Summary: public
To improve cold start performance we want to be able to avoid decoding the bundle at all. To make that happen we need to be able to generate a bundle encoded on `ucs2`. This diff adds support for indicating the encoding the Packager should use for bundling.

Summary: public
We cannot remove `local-cli` because is referenced by the global cli explicitly. If we do so, people would have to upgrate this global thin cli which will cause some pain. So, lets move `private-cli` commands into `local-cli` instead.
