Updates ODL Pipeline scripts for CSIT

Changes Include:
 - Change to TripleOInspector which only introspect a
   current Apex deployment and dump yaml config to be bundled with
   snapshots.
 - Add TripleOHelper which consists of all tripleO helper functions.
   Many this are done to virsh so the idea is to have at.
   Some point in time a libvirtHelper, or use another libvirt
   python lib. Thatsway it is a class so that we can inherit
   later on.
 - New argument for passing the SSH private key to use to connect to
   nodes is added to the service utils.
 - Some general clean up and consolidation of logic
