Changed identifiers to concept identifiers

The policy models tosca classes ToscaPolicyIdentifier and
ToscaPolicyIdentifierOptVersion can be used to identify any TOSCA
concept, not just TOSCA policies so they are renamed to
ToscaConceptIdentifier and ToscaCinceptIdentifierOptVersion
respectively.

The class ToscaPolicyTypeIdentifier is redundant and is replaced by
ToscaConceptIdentifier.

Issue-ID: POLICY-2900
Change-Id: I5df89d023949cdf0f649951dbbd81a0b30f44ef6
