chore(aws_s3 source): add custom endpoint for sqs

[serge-r]

Summary

Add ability to separate SQS endpoint from s3 configuration. It's useful for working with local environments like MinIO and ElasticMQ or non-AWS clouds.

Vector configuration

[sources.my_s3]
  type = "aws_s3"
  endpoint = "http://minio.cluster.local:9000/" 
  region = "us-east-1"

  [sources.my_s3.sqs]
  queue_url = "http://elasticmq.cluster.local:9324/queue/my-queue"
  endpoint = "http://elasticmq.cluster.local:9324/"

Use S3 region for ingestor region checks

This call now resolves the region from sqs.region, but that returned region is later stored in state.region and compared against s3_event.aws_region in handle_s3_event_record (src/sources/aws_s3/sqs.rs). If a user configures different S3 and SQS regions/endpoints (the new behavior this change enables), events from the S3 bucket region will be rejected as WrongRegion before object fetch, so the override becomes functionally broken for split-region setups.

Useful? React with 👍 / 👎.
