Script to create all dynamic properties

Given that the definition of the dynamic properties is part of the data model and is stored in the database. Therefore, even if we keep adding new properties via the API, we need to have a mechanism to be able to recreate all defined dynamic properties in a fresh instance.

Proposed solution: a yaml file (as was the case earlier ) with the definition of the dynamic properties that can be processed by a dedicated script, which runs the definitions against the API on demand. But open to any other suggestions.
