Contribute core Cray changes to Bareon

This is a contribution of features made in the scope of Cray
Bareon adoption. Even though changes affect a lot of code,
they are not breaking. To proove that we have created a functional
test that covers existing nailgun deployment flow
(see /tests_functional/test_nailgun.py)

We have made Manager a deploy_driver. Current nailgun's manager
has been moved to nailgun deploy driver, which is default. Most of
the changes made in the scope of the project are enclosed within
Ironic data driver and Ironic (swift & rsync) deploy drivers.

To make this review easier I propose the following order:
Review changes to existing code:
- review changes to object model
- review changes related to splitting deploy driver / base drivers
- review changes to common utils
Review the new code:
- review Ironic data driver
- review Ironic deploy drivers
