Use rsocket requestResponse in desktop app

Summary:
Changes the desktop app to use requestResponse for communicating with the sdk, when the sdk is on a version that can handle it.
If it's an old sdk version, just use fire and forget. We can delete this code after a while, but keeping it for now to smooth things over during migration.

This should be fully backwards compatible both ways.
