Merge "Omit service-type and service-role if empty"

Omit service-type and service-role if empty

The CreateGenericALaCarteServiceInstance flow does not use the
decomposition building block, and hence there is no service-type
or service-role for the service instance.  SO should not put
empty values into AAI; it should omit the elements completely.
