Scott Hussey d12ef71f9f Refactor orchestrator
Refactor orchestrator to break large
monolithic functions into small functions
per action.

- Update orchestrator to match new statemgmt API
- Pull most code out of __init__.py files
- Create action classes for Orchestrator actions
- Create action classes for Driver actions
- Orchestrator consumes tasks from database queue
- Additional encapsulation of task functionality into Task class
- Create shared integration test fixtures
- Fix Sphinx entrypoint so package install works
- Disable bootdata API until BootAction implementation
- Bring codebase into PEP8 compliance
- Update documentation reflect code changes
- Mark SQL #nosec for bandit
