Bug Description
When scaling the mongo role to more than seven nodes we get this:
Error: /Stage[
The problem is that all our mongo nodes are voting so we hit the limit:

We should probably find a way to make any nodes > 7 be a non voting member or some other mechanism to differentiate them (maybe an ad hoc service profile?)

We could probably add "votes: 0" added to the replset config entries of any nodes with id > 7. But this will need some thinking around scaling up/down and node replacement.
