Adding ElementSettingData association.

This only handles the case defined in section "7.3.4.2 Single-Configuration Implementation Approach" of the VSP.  Will update to handle the case(s) defined in the Resource Allocation Profile.

The handler name is a bit ugly. I suspect this name will change when I add the RASD pieces.
