Subject: [PATCH] RN: Support Multiple Packager Servers

Summary:
Adds support for multiple packager servers, which could be used to hot-reload dependencies in response to a change in the `cacheVersion`.

Currently, there is no way to:

- Create multiple `ReactPackager` servers.
- Instantiate more than one `FileWatcher` constructor (due to the "single instance" invariant).
