Public url endpoint to use for Glance versions response.

This is the public url endpoint that will appear in the Glance

"versions" response. If no value is specified, the endpoint that is

displayed in the version's response is that of the host running the
|
|
API service. Change the endpoint to represent the proxy URL if the
|
|
API service is running behind a proxy. If the service is running
|
|
behind a load balancer, add the load balancer's URL for this value.
