issue: #33103
when try to do stopping balance for stopping query node, balancer will
try to get node list from replica.GetNodes, then check whether node is
stopping, if so, stopping balance will be triggered for this replica.
after the replica refactor, replica.GetNodes only return rwNodes, and
the stopping node maintains in roNodes, so balancer couldn't find
replica which contains stopping node, and stopping balance for replica
won't be triggered, then query node will stuck forever due to
segment/channel doesn't move out.

- ReplicaManager manage read only node now, and always do persistent of
node distribution of replica.
- All segment/channel checker using ReplicaManager to get read-only node
or read-write node, but not ResourceManager.
- ReplicaManager promise that only apply unique querynode to one replica
in same collection now (replicas in same collection never hold same
querynode at same time).
- ReplicaManager promise that fairly node count assignment policy if
multi replicas of collection is assigned to one resource group.
- Move some parameters check into ReplicaManager to avoid data race.
- Allow transfer replica to resource group that already load replica of
same collection
- Allow transfer node between resource groups that load replica of same
collection

Since querycoord need index meta information from datacoord only, broker
shall use `ListIndexes` to skip segment index building check logic in
datacoord
This PR is also related to #30538, in which DescribeIndex caused lots of
memory usage and lead to OOM eventually
