Restructure mistral-extra repo

* "examples" file tree should not be Python packages
* Examples should have their own dependencies, if needed, not centralized

Next steps:
* Prepare a layout for storing OpenStack actions

Depends-on: Id8e5d55e34ec3b3d555b5482e13f99c2561e871e
Partially implements: blueprint mistral-custom-actions-api
