Errors Initializing and Starting Up Policy Engine (Configuration Hints, Orca/CloudDriver/Front50)

Issue

Policy Engine has been implemented with settings in Operator/Halyard, but it is not starting up and is causing errors in the initialization.  Example may look like something below:

The typical cause is a non-static @Bean method with a BeanDefinitionRegistryPostProcessor return type: Consider declaring such methods as 'static'.

Cause

Configurations on Policy Engine require a complete list of declarations.  It can be easy to miss a declaration.
