enhance: Implement flusher in streamingNode (#34942)
- Implement flusher to:
  - Manage the pipelines (creation, deletion, etc.)
  - Manage the segment write buffer
  - Manage sync operation (including receive flushMsg and execute flush)
- Add a new `GetChannelRecoveryInfo` RPC in DataCoord.
- Reorganize packages: `flushcommon` and `datanode`.

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.
