Some service clients do not respect the old OS_ENDPOINT_TYPE
parameter, instead only supporting the newer fashion of
OS_INTERFACE which is viewed as less confusing. This adds support
for that option.
Failure to include this causes SSL certificate errors when the
service clients attempt to use the public endpoint with a self-
signed certificate on defaulted installs, particularly AIOs.
This error can be demonstrated by trying to use the Gnocchi or new
Aodh clients from a utility container, though only the Gnocchi
client is currently installed in the integrated build.
