Major Description
Delete multiple objects with sending XML message to the bucket?delete endpoint is implemented in HDDS-701 according to the aws documentation at https://docs.aws.amazon.com/AmazonS3/latest/API/multiobjectdeleteapi.html
As the documentations writes:
{{ By default, the operation uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete operation encountered an error}}
In the quiet mode (which is an XML element in the input body) we return the XML only in case of errors based on this paragraph. Without any error we returned *with *empty body.
But during the executions of s3a unit tests I found that the right response is an empty XML document instead of empty body (in case of quiet mode + without any error)
<?xml version="1.0" encoding="UTF-8"?> <DeleteResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
Some of the s3a unit tests are failed as without XML response the parsing was unsuccessful.
