http https option

[mkbsugita]

add http or https option

    var httpStr = 'http';
    if (useSSL) {
      httpStr += 's';
    }
    final endpoint = '$httpStr://$bucket.s3.$region.amazonaws.com';

Out of curiosity, what's the use case for supporting non HTTPS requests to S3?

I commented in Isseu but

this pattern

https://docs.aws.amazon.com/AmazonS3/latest/userguide/WebsiteEndpoints.html
Does not support SSL connections

Other plugin also supports useSSL option.
