[Feature] - virtual host bucket addressing

[benmcclelland]

Describe the solution you'd like AWS allows for S3 requests to have the bucket as part of the host instead of the query. This allows load balancing and service redirection based on DNS. It would be nice to look into what it would take to allow the gateway to accept virtual host address requests.
