issue: #33550
cause concurrent issue may occur between remove parition in target
manager and sync segment list to delegator. when it happens, some
segment may be released in delegator, and those segment may also be
synced to delegator, which cause delegator become unserviceable due to
lack of necessary segments, then search/query fails.
this PR make sure that all write access to target_manager will be
executed in serial to avoid the concurrent issues.

- 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
