Implementation of ATTS-66 to update service catalog with Apigee endpoints.  Distinguish between different URL types in service catalog, and instruct openstack services to use internalURL instead of public.
ATTS-66: Somewhat messy workarounds to support Apigee endpoints listed in catalog for adminURL and publicURL.  This leaves only one URL left for internal openstack (internalURL), whereas it needs two.
ATTS-66: Additional updates for this issue to distinguish between Apigee endpoints in catalog vs openstack config file parameters.
