Feature request : QueryCondition.relationCountGT / .relationCountLT #1110

First things first, I've really been enjoying the new query API as well as the new features of v3.5.0. That helps me building a cleaner and faster data layer. Thanks guys for listening to us~

I'd love to have two extra methods akin to the new relationCount query condition to check if the relation count is greater than or lower than a certain number; typically to test if entity X has existing relations (i.e. > 0) or if it reaches a given threshold.

Would that be possible ?
