List<Endpoint> endpoints() {
        return origEndpoints;
    }
Returns the original list of endpoints this priority set was created with.
This method acts as a temporary measure to keep backwards compatibility with
{@link SubsetLoadBalancer}. It will be removed once {@link SubsetLoadBalancer}
is fully implemented.
