Allow enable_s3_backup = false for opensearch

[maordavidov]

The module enforce s3 backup for opensearch. When using a scenario such logs destination (fluentbit -> firehose -> opensearch) the usage of s3 backup is not needed.

Is it possible to allow it as optional instead of required?

hi @maordavidov ,

Today i had some time to looking for this. I'm not sure if i understand correctly your issue. It seems S3 Backup is mandatory for Opensearch destination.

Please re-open the issue if i didn't understood correctly what you are asking for.

Thanks.
