issue: #35821 After collection loaded, if we need to increase/decrease collection's replica, we need to release and load it again. milvus offers 4 solution to update loaded collection's replica, this PR aims to dynamic change the replica number without release, and after replica number changed, milvus will execute load replica or release replica in async, and the replica loaded status can be checked by getReplicas API. Notice that if set too much replicas than querynode can afford，the new replica won't be loaded successfully until enough querynode joins. --------- Signed-off-by: Wei Liu <wei.liu@zilliz.com>
