Thomas Spatzier eae9a2ad3f Factor Schema out of properties.py for re-use ... There is currently some function duplication in Heat for schema validation. There is properties.Schema and a ParamSchema class which do mostly the same, but each with their own code. It would be good to have a common implementation for property and parameter validation with only property or parameter specific code implemented in sub-classes. The current Schema class in properties.py cannot be used in parameters.py due to cyclic import dependencies that would arise. This patch factors the Schema class and Constraint classes into their own file which can then be imported by both properties.py and parameters.py. For property schema specific code, a class PropertySchema is introduced as derived from the common Schema class. The code of the Schema and Constraint classes is unchanged except for absolutely refactoring work. In a subsequent patch, I plan to provide the code to base ParamSchema on the common Schema class.
