> Define the BufferListener interface to replace EventListener in BufferProvider

>
> Currently the {{EventListener}} is used in {{BufferProvider}} to be notified
> of buffer available or destroyed pool.
> To be semantic clearly, we define a new {{BufferListener}} interface which
> can opt for a one-time only notification or to be notified repeatedly. And we
> can also notify the pool destroyed via explicitly method
> {{notifyBufferDestroyed}}.
> The {{RemoteInputChannel}} will implement the {{BufferListener}} interface to
> wait for floating buffers from {{BufferProvider}}.
