Dynamic key_path_prefix in S3 DLQ

[graytaylor0]

Is your feature request related to a problem? Please describe. As a user of the S3 DLQ, I would like to dynamically determine the prefix to send failed documents to with Data Prepper expressions, similar to how the S3 sink path_prefix can be dynamic

Describe the solution you'd like

sink:
  - opensearch:
       s3:
         dlq:
           key_path_prefix: "my-${/key}-prefix/"

Alternative Solution An alternative that would be more useful would be to create a pipeline DLQ that can send to the s3 sink, which supports dynamic path prefix
