This test brings larger clusters near the quorum point (50%).
In addition, it will test doing starts and stops at the same time.
Here is how I think it should work:
- loop over the nodes and decide randomly which will be up and which
will be down Use a 50% probability for each of up/down.
- figure out what to do to get into that state from the current state
- in parallel, bring up those going up and bring those going down.
