Mark Oswald 90f9f48498 add reset-cache command to bundle
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
