Delete terms not used in the SAREF extensions
**Situation:** Some terms are not used in the SAREF extensions, but may be used by users of SAREF:
- `saref:hasDescription`
- `saref:hasName` (hasName is now actually encoded inside the URI of the class)
- `EnergyRelated`, `FunctionRelated`, `BuildingRelated`
**Proposal:** To delete these terms, and anywhere in the spec where `saref:hasDescription` is used, recommend the use of `dcterms:description` instead.
**Status:**
- `hasDescription` and `hasName`: agreed during SmartM2M-RG Meeting about 2 NWIs SAREFv3 and SAREF Com Framework V2 2019-04-08
- other classes: agreed during SmartM2M-2nd RG Meeting about 2 NWIs SAREFv3 and SAREF Com Framework V2 2019-05-06
