Open Stack

Hi all,

I use vitrage without any root graph (In my case there is no root).
Until few days ago I was able to request topology of type graph with no problems.
But I can't, I got 404, and the log says it can't find openstack.cluster node.

I think it have the problems since these commits : I1189047849f714d8435414cc48098d71837b3ed0, I1438713136c0177282e8ee8e19a651af5590feef
