AWS SDK V2 - AuditFailureExceptions aren't being translated properly

ITestS3AHugeFilesNoMultipart is failing because the AuditFailureException variant raised in the sdk handler is being wrapped as it makes its way back to the s3a code -but S3AUtiis.translateException() isn't looking at the inner cause.

looks like aws v2 sdk class .GenericMultipartHelper.handleException is wrapping an SdkException with a SdkClientException even though it is not needed.

we probably have to start looking at the inner cause of any exception during translation to see if that is also a AuditFailureException.
