Change S3 provider endpoint

[liquid36]

Hi! i want to use another S3 provider than AWS. But it is not possible to set S3_ENDPOINT by env variables.

I'm not expert in Java but i made some research, it seems to be possible by doing something like this:

String endpoint = System.getenv("AWS_S3_ENDPOINT");   
URI endpointUri = endpoint != null ? URI.create(endpoint) : null;

S3Client.Builder builder = S3Client.builder()
    .region(Region.US_EAST_1)
    .credentialsProvider(DefaultCredentialsProvider.create());

if (endpointUri != null) {
    builder.endpointOverride(endpointUri); 
}

S3Client s3 = builder.build();

Could you implement it?
