Summary:
Flipper exposes a call() api to plugins which lets them call their sdk component, and it returns a promise with the response.
Currently this is done by sending a fireAndForget request, noting the id of the request, and then receiving fireAndForget requests and matching up the ids to give the result back to the right plugin promise.
Instead, it will be simpler to use rsocket requestResponse, instead of fireAndForget, which is for this exact use case. This diff adds a requestResponse handler to the SDK, so that it can deal with such requests and respond accordingly, while preserving the current functionality if it receives a fireAndForget.
So this part is backwards compatible and should be safe to land in isolation.
A later diff will change the desktop app to use requestResponse, which may not be backwards compatible, so that will have to be deployed more carefully.
