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. Reviewed By: fromcelticpark Differential Revision: D7845136 fbshipit-source-id: f003f98a2607c8354c427a7e60e01e19e20295b1
