Breaking changes

* We have split `new_app` method of origin backend to three specific methods:
- `deploy_image` for deployment of an image.
- `create_new_app_from_source` for deployment of applications using source-to-image from local or remote source.
- `create_app_from_template` for deployment of applications using OpenShift templates.

New features

* Troubleshooting and debugging of OpenShift backend is now easier because of new methods `get_logs` and `get_status`.

Fixes

* Documentation is updated and now includes OpenShift and Kubernetes backends.
* Fixed race condition when starting docker containers via binary.
* Nspawn backend improvements:
- Changed default image location to `/opt` to avoid issues with brtfs and using loopback device.
- Do not use pull-raw and importing via machinectl.
