    Register a system offer group (an offer group that referenced by code). Returns the OfferGroup instance.

    To get / create a system offer group, call this function somewhere in your code base and assign the
    result to a constant. The return value is a lazy evaluated function which will, on-first-access, create the
    OfferGroup. On subsequent accesses, it will simply fetch the offer group and return it.
