    [CELEBORN-2119] DfsTierWriter should close s3MultipartUploadHandler and 
ossMultipartUploadHandler for close resource
    
    ### What changes were proposed in this pull request?
    
    `DfsTierWriter` should close `s3MultipartUploadHandler` and 
`ossMultipartUploadHandler` for close resource to avoid resource leak for 
destroy file writer.
    
    ### Why are the changes needed?
    
    `DfsTierWriter` does not close `s3MultipartUploadHandler` and 
`ossMultipartUploadHandler` in `closeResource`.
    
    ### Does this PR introduce _any_ user-facing change?
    
    No.
    
    ### How was this patch tested?
    
    CI.
    
    Closes #3433 from SteNicholas/CELEBORN-2119.
