issue: #32910 see also: #32911 when channel exclusive mode is enabled, replica will record channel node info in meta store, and if the balance policy changes, which means channel exclusive mode is disabled, we should clean up the channel node info in meta store, and stop to balance node between channels.

#note that there is a possibility of Milvus crashing when the actual memory demand exceeds the value set by maxMemSize.
