Code Issues Proposed changes

Add scheduling thread to nodepool builder

Browse Source 
This is the building block for the structure that nodepool builder will
take going forward. It introduces a new scheduling thread, and moves all
current build and upload worker threads underneath that. A new thread
for receiving ZooKeeper watch events is also introduced.

This code will run, but isn't currently functional because the worker
and watch threads just sleep. Later reviews will begin to add the
functionality.

A supporting developer's guide is added that shows the main components
and communication channels.

Since this is a partial implementation, several tests have to be
temporarily disabled until the ZooKeeper functionality is in place.
