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.
