enhance: Add ListIndexes API from datacoord (#31104)
See also #31103

This PR add `listIndexes` API for datacoor server to list all indexes
for provided collection.
Comparing to the existing `DescribeIndex` API, the new one does NOT
check the segment index building progress to ease the burden when
invoking it

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.
