This JSON rule is equivalent to the following MinIO Client command:
```
mc ilm rule add --noncurrent-expire-days 30 --noncurrent-expire-newer 5 --prefix "user-uploads/" myminio/mydata
```

#### 3.2.a Automatic removal of noncurrent versions keeping only most recent ones immediately (MinIO only extension)
