Use disabled suffix for disabled service names

Use disabled suffix for disabled service names

This changes both the service names and the file names for disabled
services, adding the 'disabled' suffix to them.

This comes with the reasoning that, if a service requires a disabled
service, and checks for the name in the "service_names" hiera entry, it
will appear as if the service was enabled, when it's actually not. So
changing the name and using this convention prevents that issue.
