Fix delete node not aware of merged segments error (#14190) 
This PR made merge gracefully remove merged segment by moving
them into `compactedSegments`

And everytime when delete_node operates, if compactedSegments
have contents, delete_node will replace the latest segment in delBuf
merged from the merged segments, and truely remove the compactedSegments

Fixes: #14085

  • Message stream: receive messages and publish imformation
  • Root Coordinator: get the latest unique IDs.
  • Data Coordinator: get the flush information and which message stream to subscribe.
