enhance: Solve channel unbalance on datanode (#34984 )

issue: #33583
the old policy permit datanode has at most 2 more channels than other
datanode. so if milvus has 2 datanode and 2 channels, both 2 channels
will be assign to 1 datanode, left another datanode empty.

This PR refine the balance policy to solve channel unbalance on 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.
