    Description

      On uploading a file through s3g an ETag header should be provided:

      • in the case of a single file/part upload it represents MD5 of the file content
      • if the file will be uploaded using a multipart upload then the ETag of the object is computed as MD5 of all individual part checksums: 
        //	 e1 = MD5(part-1)
//	 e2 = MD5(part-2)
//	...
//	 eN = MD5(part-N)

//	ETag = MD5(e1 || e2 || e3 ... || eN) || -N
//	For example: ceb8853ddc5086cc4ab9e149f8f09c88-5

      Computed ETag should be stored as a key metadata
