Add overlord monitor for monitoring leadership status.

This ask is that a Monitor be put in place on the overlord (and probably coordinator) that reports the leadership status of that part of the service.

That should be there already. /leader

@drcrallen do you mean a separate monitor vs an http endpoint? what's the use case?

[drcrallen]

I mean a com.metamx.metrics.Monitor that emits information about if the node is currently leader. We're seeing some leadership issues when the zk connection has problems. And having information about if a node thinks it is leader would have been helpful.
