Add Control Loop Coordination policy.

Refactor code to support multiple pip engines.
Add pip engine for outcome.
Modify LegacyGuardTranslator to use coordination translator's
convertPolicy function when processing coordination guard.
This version of convertPolicy intentionally uses string
replacement on template-like xacml coordination guard to
enable future support for API-based creation of new coordination
guard types.
Bug fixes and code cleanup.

* Unused imports, sonar problems.
* Consolidation of getAttribute method
* Only use TypedQuery for Pips
