AC Plugin Enhancements

[MoonWorm]

• Generate 'meta' section with details about what was anonymized and why
• Think about ABAC (Attributes Based Access Control) approach that can give full flexibility: add custom Map<String, Object> that users can set from HttpRequest (JWT, for example) in PrincipalResolver. Extend AccessControl annotation with abac handler - class type that encapsulates evaluation logic against this map. Similar to Path and Resource Owner for inbound requests.
• Make these behaviours configurable via application.properties
• Reflect in Documentation.
