issue: #37172 - add redo interceptor to implement append context refresh. (make new timetick) - add create segment handler for flusher. - make empty segment flushable and directly change it into dropped. - add create segment message into wal when creating new growing segment. - make the insert operation into following seq: createSegment -> insert -> insert -> flushSegment. - make manual flush into following seq: flushTs -> flushsegment -> flushsegment -> manualflush. --------- Signed-off-by: chyezh <chyezh@outlook.com>
