(web) service revision - replace controlledTerms/Service with core/WebService(Version)

[apdavison]

The addition of WebService and WebServiceVersion make the controlled term Service redundant.

Currently, Service is only used in the ServiceLink schema.

Checklist: does a WebService and at least one WebServiceVersion exist for all the controlled term instances?

Question: should ServiceLink link to WebService, to WebServiceVersion, or allow both? Unlike software, older versions of web services are often no longer available; also, it would be a lot of work to update a lot of service links every time a new version of a web service is released. Therefore, it would be better to link to WebService; however, there may be scenarios where a service link only works with a specific version. Overall, therefore, I suggest allowing a linkage to either.
