issue: #30647
- 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

issue: #29677#29838
during get shard leaders, if qeurynode doesn't ack the heartbeat than
10s, querycoord will treat it as unavailable, and won't return shard
leader on it. but when querynode has a full cpu usage, it's easily to
stuck for more than 10s without ack the heartbeat, which cause no shard
leader to search/query.
This PR remove heartbeat lag logic during get shard leaders

sync distribution by rpc will also call loadSegment/releaseSegment,
which may cause all kinds of concurrent case on same segment, such as
concurrent load and release on one segment.
This PR add leader_checker which generate load/release task to correct
the leader view, instead of calling sync distribution by rpc
