refactor(dl): Make Widevine CDM config optional 

With this change you no longer have to define/configure a CDM to load. This is something that isn't necessary for a lot of services.

Note: It's also now less hand-holdy in terms of correct config formatting/values. I.e. if you define a cdm by profile for a service slightly incorrectly, say a typo on the service or profile name, it will no longer warn you.
