New Optimization Policy

This is the new Optimization Policy to support the Integration of
the OOF Policy Model into the Policy Platform.

Added changes from Frank Wang to fix the following issues with existing Model
Parser:
1. TOSCA Rendering issues
2. Matching Attributes support
3. ImportModelAPI to support TOSCA model upload via REST API

Running local Sonar tonight to start fixing Sonar issues

Added changes per review comments and fixed Sonar issues
