The rsc_colocation constraint in <2.0.8 is bi-directional. If one can't
run, the other side is assumed to also be unable to run. 

(Another effect of this is causing an entire group to stop as opposed to
bringing the group partially online up to the failing resource, at
least.)

In >=2.0.8, it is no longer bi-directional by default and behaves as
you'd expect it to.
