issue #42492 - streamingcoord start before old rootcoord. - streaming balancer will check the node session synchronously to avoid redundant operation when cluster startup. - ddl operation will check if streaming enabled, if the streaming is not enabled, it will use msgstream. - msgstream will initialize if streaming is not enabled, and stop when streaming is enabled. --------- Signed-off-by: chyezh <chyezh@outlook.com>
