Fix explicit endpoint configuration

When trying to specify the endpoint type in the identity service catalog
to use for communication with OpenStack services an outdated
configuration option was written: endpoint_type was replaced by
interface in aodh.

This change therefore also deprecates the aodh::auth::auth_endpoint_type
parameter in favor of a new aodh::auth::interface parameter.
