Add node status to API object.

@smarterclayton @lavalamp I'm not sure if this is enough to get it work.  Beat me up.  

 @smarterclayton Should I also take care of v1beta3?

Oh, yeah, definitely.  The ConditionFull itself is not intuitive, but combine with Kind, it makes more sense
```
	node.Status.Conditions[0].Kind = NodeReachable
	node.Status.Conditions[0].Status = ConditionFull
```
=> FullReachable
