[SUGGESTION] use default AWS authentication properties

[stefanofornari]

Task Description

I see that to use s3fs-nio, an amazon.properties with s3fs.* properties is used to configure access to the service.
It would be great, if it instead used (or in addition to) the standard AWS Default Credentials Provider Chain.

Tasks

The following tasks will need to be carried out:

• Investigate how the AWS Default Credentials Provider Chain works.
• Consider whether this would work.
• Implement the necessary changes.
• Add tests.

@stefanofornari ,

Thanks for the suggestion!

As mentioned on the other issue you raised, please, don't ignore our issue template.

Sorry about that. I haven't found a template for discussions/requests. Which one should I have used?
thanks in advance

No problem. When you create a new task/bug report, it already comes with pre-populated text for you and you just have to add the description.

This is something on our radar, but at the moment we'd like to focus on doing the release first.

At this moment I'm not sure if this won't be a breaking change, because some members of the community are already using s3fs-nio with the properties above. I believe we should revisit this a bit later.

This one is actually already implemented, but it appears it was not properly documented.
The org.carlspring.cloud.storage.s3fs.S3Factory#getCredentialsProvider() method attempt to lookup the s3fs properties and if it does not find them will proceed with looking them up via the AWS SDK DefaultCredentialsProvider.
