-------------------------------

> When the user does not specify a ZooKeeper quorum to run Giraph on, the ZooKeeperManager
creates one. This factors out the boilerplate that handles this additional process and its
lifecycle so that various pluggable versions of this process instantiation can be implemented
and fed to the ZKManager via a factory depending on the nature of the underlying cluster.
> By implementing the ZooKeeperProcessBuilder interface, one will now be able to implement
the creation/mangement of a new, job-local ZK instance using any underlying resourcing mechanism
one chooses (including, I hope, YARN.)
> Passes mvn verify, etc.
