[Filebeat] Enable S3 support for other clouder than AWS's

[rhanka]

Describe the enhancement:
Many cloud service and private resources handle s3.
Most s3 libs support such alternate s3 services, like logstash
Since bucket_arn feature, SQS isn't a dependency anymore so using any S3 should be possible.

Describe a specific use case for the enhancement or feature:
Well i'd love to retrieve logs stored to Scaleway S3 buckets.
I didn't manage to use https://s3.fr-par.scw.cloud s3-compat endpoint with filebeat, whearus using it with logstash or vector.dev is possible
