1. Fix replicator cannot stop if error occurs on replicate stream RPC. 2. Simplify replicate stream client. 3. Enhance replicate config validator: 1. Compare the incoming replicate config, cluster attributes must not be changed. 2. Cluster URI must be unique. 3. Remove the check of pchannel prefix. issue: https://github.com/milvus-io/milvus/issues/44123 --------- Signed-off-by: bigsheeper <yihao.dai@zilliz.com> Co-authored-by: chyezh <chyezh@outlook.com>
