Don't include "nullVersion" in swagger API

Swagger sitll uses jackson, thus it is including
ToscaPolicyIdentifierOptVersion.isNullVersion() in the API that it
generates.  Added @JsonIgnore annotation to prevent it from being
included.  Similar issue with get/setVersion() in PdpGroup.
Created POLICY-1653 to remove the isNullVersion() method altogether in
El Alto.
