Add One To Zillions relation

[brauliodiez]

In MongoDB on a one to many relation ship when the many side can contain thousands of items we can use the one to zillions marker, we could implement this in the following way

• Creating/Update the relation, if the relation is 1:M or M:1 show a check box indicating Is a Zillions relation

• On the Canvas we can show instead of the fork, the zillions indicator

This needs further refinement
