S3Proxy is not compatible with official AWS' extended library

[bwiercinski]

pass4s is sending following payload on the SQS if the message is considered large:

{"s3BucketName": "bucket", "s3Key": "key"}

This format is not compatible with the official AWS' extended client which is putting a message with the following format:

["software.amazon.payloadoffloading.PayloadS3Pointer", {"s3BucketName": "bucket", "s3Key": "key"}]

S3Proxy Addon was designed from the beginning to be compatible, so I would consider it as a bug.

Another difference is with message attributes, but this is less important as the attribute is optional I think:

pass4s:
-{"ExtendedPayloadSize":{"StringValue":"22","DataType":"String"}}
aws extended client:
+{"ExtendedPayloadSize":{"StringValue":"22","DataType":"Number"}}
