Add native delta client for Metro

Browse Source 
Summary:
Adds C++ delta client that keeps modules in memory, and can be used as a RAM bundle.

For now, this client expects a `folly::dynamic` object as payload for patches, i.e. the JSON response retrieved from Metro needs to be parsed with `folly::parseJson` by the caller.

In the future, we will replace JSON with a streaming friendly binary format.
