Open Stack

Yun Mao and some fine folks from IBM have developed a modular
healthcheck system, proposed to Nova here:

https://review.openstack.org/#/c/10903/

I think it's worth looking into. I know Yun and folks from IBM are
interested in porting this into openstack-common where appropriate after
it bakes in Nova for a while. There is a driver model used, with a
ZooKeeper-based driver implementation.
