Override retry strategy for AWS S3 client

[julianhowarth]

We use the AWS S3 client extension to access objects on S3. We've recently been having issues across a number of our services where the default AWS s3 async client has had issues connecting and downloading objects. In line with our other, non-Quarkus services, we would like to modify the retry policy to make it more robust.

Essentially we want to do:

S3AsyncClient buildS3AsyncClient() {
    return S3AsyncClient.builder()
        .region(config.s3Region())
        .overrideConfiguration(o -> o.retryPolicy(buildRetryPolicy()))
        .build();
}

private  RetryPolicy buildRetryPolicy() {
  ...
}

• Is this possible to do with the extension in some way or do we basically need to build the client directly ourselves?
• If we do build directly, is there any point in keeping the dependency on the extension?
