Liang-Chi Hsieh cf133e6110 [SPARK-26604][CORE] Clean up channel registration for StreamManager ... ## What changes were proposed in this pull request? Now in `TransportRequestHandler.processStreamRequest`, when a stream request is processed, the stream id is not registered with the current channel in stream manager. It should do that so in case of that the channel gets terminated we can remove associated streams of stream requests too. This also cleans up channel registration in `StreamManager`. Since `StreamManager` doesn't register channel but only `OneForOneStreamManager` does it, this removes `registerChannel` from `StreamManager`. When `OneForOneStreamManager` goes to register stream, it will also register channel for the stream. ## How was this patch tested? Existing tests. Closes #23521 from viirya/SPARK-26604.
