Bind to higher port numbers

When you change the user in a Dockerfile using USER default, the process inside the container runs with the permissions of that user. In COS, only the root user (or processes with elevated privileges) can bind to ports below 1024. So, if our application is trying to bind to a port below 1024, and it's not running as root, we are getting an error.
