Adds Utility functions and failure logging

Patch adds helpful utility functions and automatic parsing of heat
output into a readable format indicating where a failure is in a
deployment.  Example: http://fpaste.org/354210/

New opnfv-util function allows a user to interact with a deployment
easily:
 - opnfv-util undercloud <user> connects user to undercloud VM
 - opnfv-util debug-stack parses the heat failure output

Above arguments also accept partial matches.
