Patterns and Engines

Registered by Ivan Melnikov on 2013-08-16

We want:

- split flows into patterns (that describe flow structure) and engines (that actually run said structure);
- provide a framework to ease creation of new patterns and engines;
- integrate best parts and ideas from blocks proposal by Anastasia Karpinska (https://review.openstack.org/36472).
