Onyxia api must return only charts installed as a part of the current region.

Some instance may want to use the namespace for 2 regions. We should return only charts from the current region.

@fcomte Should we add a region metadata to helm values much like friendlyname, owner, share ... ?

I think yes, this injection should be done on user side or server side. (We do none server side injection at the moment)
