Initial commit of replication

-> Listens to health store for status of all health checks assigned
to a service in the current cluster
-> Sorts nodes to update by health - healthy nodes are updated last
-> Attempts to update forever until all nodes report healthy. Can
cancel with the stop channel.

Still needs both unit and integration testing.
Address comments, make simple test pass
