Have you read the spec in question [1] and if so, does it suit your needs?

It specifically calls out the need to honor the existing glance 
api_servers config option, but it says we are going to honor for a 
release but deprecate the other service endpoint override options in 
place of using the service catalog.

Are there other specific services that you need to override which a 
private/internal endpoint type in the service catalog doesn't work for you?
