enhance: use recovery+shardmanager, remove segment assignment interceptor (#41824)
issue: #41544

- add lock interceptor into wal.
- use recovery and shardmanager to replace the original implementation
of segment assignment.
- remove redundant implementation and unittest.
- remove redundant proto definition.
- use 2 streamingnode in e2e.
