> Async methods like asyncLedgerCreate and Open shouldnt be throwing
> InterruptedException and BKExceptions.
> The present method signatures lead to messy application code since one is
> forced to have error handling code in 2 places: inside the callback to
> handler a non-OK return code, and outside for handling the exceptions thrown
> by the call.
> There should be only one way to indicate error conditions, and that should be
> through a non-ok return code to the callback.
