#service_type_name(account_name, name) ⇒ Object

lets identify the real service type name create support for account config to have a section called :service_catalog This section will identify mappings for keys like : object_storage, compute, block_storage, cdn

networking, dns, and load_balancer

The values can be the real names of the offerings. This enables private cloud implementations to have service catalog names that make more sense for there implementation.
