When i "mkdir /dfs/buckets/newbucket", remote s3 will create many "newbucket-xxxx" buckets.

System setup

Same as: #2465

Info:

/fastdfs : Mount of "Local Weed"
/dfs: Mount of "Remote Weed"

Describe the bug

When:

mkdir /fastdfs/buckets/newbucket/ (On Local Server)

I got ❌:

ll /dfs/buckets/ (On Remote Server)

drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-1317
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-1521
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-2486
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-2595
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-2863
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-3108
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-3293
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-4312
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-4410
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-5927
drwxrwxrwx 1 root root 0 Dec  5 23:40 'newbucket- 633'
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-8048
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-8791
drwxrwxrwx 1 root root 0 Dec  5 23:40  newbucket-9973

Expected behavior

When:

mkdir /fastdfs/buckets/newbucket/ (On Local Server)

I want ✅:

ll /dfs/buckets/ (On Remote Server)

drwxr-xr-x 1 root root 0 Dec  5 23:40 newbucket

-createBucketWithRandomSuffix can fix this.
