Converted the Beacon API service to Futures
- Added SSZ encode for HeadResponse
 - Converted all of the /beacon/ endpoints to return BoxFut instead of ApiResult
 - Wrapped all of the '?'s in a new macro try_future!()
 - Copied the try macro to try_future, so that a boxed future can easily be returned.
 - Replaced all of the response serializations to use the new success_response
