Refactor TaskFlow implementation
Code that's using TaskFlow in Cinder is almost 2 years old. There's a lot of outdated comments and redundant code paths. Additionally some limitations of TaskFlow led to ugly workarounds that are making the code hard to understand. At the summit team agreed to have time for refactoring till around Liberty-1 and then decide if we want to integrate with TaskFlow further.
This BP aims to clean up and refactor each of create_volume workflows (c-api, c-sch, c-vol). To cover TaskFlow limitations problem we want to step up and work with TaskFlow community to address the gaps and refactor Cinder's code to use latest features.
All these efforts should make current code easier to understand and make further TaskFlow adoption possible.
