cmsdk: Mandate telephony feature xml's for service implementation.

The feature xml plays two roles:

      1) To allow sdk interface (constructor) to throw when system
      service is unavailable. This allows for clearer platform
      development debugging.

      2) To allow for simpler disambiguation of what services to
      instrument in a modular environment.
