Augment Dynamic UI with DSL object model templating

Registered by Timur Sufiev on 2014-03-17

In Murano pre-0.5 days Dynamic UI rendered forms that mapped to plain object model: every additional form step simply added some attributes to the list which then was finally passed to murano-api. With the introduction of Object Inheritance & Composition object model passed to murano-api has changed: it is no more a plain list, but is a nested dictionary/list instead.

The plan is to leave forms as they are now (a sequence of steps, excluding changes addressed by https://blueprints.launchpad.net/murano/+spec/new-web-ui-prototype ), and then convert plain data to nested using templates transformations defined in the same Dynamic UI file/blob.
