feat(boto3): Add response, retry, and error span attributes

[pabloDeputter]

Description

Add generic response, retry, and error attribute enrichment to boto3 spans. Previously, only recorded request and client metadata was instrumented; information after the call such as HTTP status, retry count, etc was omitted. The new attributes follow the OTel AWS SDK conventions.

Changes

• add SPANDATA consts: AWS_REQUEST_ID, AWS_EXTENDED_REQUEST_ID, HTTP_REQUEST_RESEND_COUNT, and ERROR_TYPE.
• add _get_response_attributes() to extract http.response_status_code, http.request_resend_count, aws.request_id, and aws.extended_request_id.
• Add erorr.type from ClientError.Eror.Code or the exception class, without recording error messages.
