[Bug]: The directory-based-walk-api of Milvus metaKv can see other directories

[chyezh]

Is there an existing issue for this?

• [X] I have searched the existing issues

Environment

- Milvus version: master-29ddb10e8caea97e52ccf815a48f1f1aead72157
- Deployment mode(standalone or cluster): 
- MQ type(rocksmq, pulsar or kafka):    
- SDK version(e.g. pymilvus v2.0.0rc2):
- OS(Ubuntu or CentOS): 
- CPU/Memory: 
- GPU: 
- Others:

Current Behavior

func (kv *etcdKV) WalkWithPrefix(prefix string, paginationSize int, fn func([]byte, []byte) error) error {
    start := time.Now()
    prefix = path.Join(kv.rootPath, prefix)

    batch := int64(paginationSize)
    opts := []clientv3.OpOption{
        clientv3.WithSort(clientv3.SortByKey, clientv3.SortAscend),
        clientv3.WithLimit(batch),
        clientv3.WithRange(clientv3.GetPrefixRangeEnd(prefix)),
    }

WalkWithPrefix and LoadWithPrefix will truncate the last / of prefix parameter by calling path.Join. so the WalkWithPrefix can see the other directories.
