Add support for virtual hosts for non-aws s3 services

[yan-sh]

For non-aws services i can only use path style address even if my service support virtual hosts. I think it can be done by adding some field to ConnectionInfo that can be optional (if there is no value it can parse connectionHost as it is implemented now).

To resolve the issue of being restricted to path-style addressing for non-AWS S3 services that support virtual hosts, the recommended solution is to configure a specific environment variable on your MinIO server. By setting the MINIO_DOMAIN environment variable to your server's domain name, you enable MinIO to correctly interpret and handle virtual host-style requests from clients. This configuration allows the server to support both path-style and virtual-host-style requests simultaneously. For instance, you would execute a command like
export MINIO_DOMAIN=yourdomain.com
minio server /data

in your terminal before starting the MinIO server. This is the standard and widely accepted method for enabling this functionality for S3-compatible services connected to MinIO.
