Functional Testing infrastructure

[rhettg]

Let's develop testing utilities for end-to-end testing of Tron.

Ideally i'd like to be able to write a test, which easy to use interface which:

• Starts a trond instance
• Kill or restart trond instance
• Configures and manages jobs/actions via www api
• Executes commands such as tronview and tronctl (and can check output)
• A few provided commands for actions which do things like : Exit failure, Exit success, Provide a service (daemonize, w/pid-file), stream logs of io

These functions should be usable within a standard testify test case.

Need more test cases, but this now exists.
