enhance: add create segment message, enable empty segment flush (#37407) 
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.

Data Coordinator

Data cooridnator(datacoord for short) is the component to organize DataNodes and segments allocations.

Dependency

  • KV store: a kv store has all the meta info datacoord needs to operate. (etcd)
  • Message stream: a message stream to communicate statistics information with data nodes. (Pulsar)
  • Root Coordinator: timestamp, id and meta source.
  • Data Node(s): could be an instance or a cluster, actual worker group handles data modification operations.
