Add functionality to add old buckets to etcd on startup
Buckets already present on a Minio server before it joins a bucket federated deployment will now be added to etcd during startup. In case of a bucket name collision, admin is informed via Minio server console message. Added configuration migration for configuration stored in etcd backend. Also, environment variables are updated and ListBucket path style request is no longer forwarded.

will be used to resolve bucket from DNS. For example if you have a bucket such as `mybucket`, the

client can use now `mybucket.domain.com` to directly resolve to the right cluster. `MINIO_DOMAIN_IP`
|

client can use now `mybucket.domain.com` to directly resolve to the right cluster. `MINIO_PUBLIC_IP`
|

points to the public IP address where each cluster might be accessible, this is unique per each cluster.
