First commit of TAPI 2.5 final draft model

All modules: Deleted all interfaces.
TapiOam, TapiDigitalOtn (OAM) and TapiPhotonicMedia (OAM): Several changes (new classes OamJobService and OamJobDescriptor, completely changed the PM reporting model, deprecated CurrentData and decoupled HistoryData from OAM Job, harmonised embedded and independent provisioning modes).
TapiTopology: some Link parameters moved to RW to support link management use cases.
TapiCommon: enhanced the optical PM parameters
TapiCommon: PmParameterValue enhanced with MetricValueType
Cleaned some garbage of TapiPhotonicMedia.uml, likely dangling references to Geolocation, moved to TapiEquipment.
