DATACMNS-365 - Enhanced auditing subsystem to work with accessor annotations.

Added a MappingAuditableBeanWrapperFactory to be able to use themapping metamodel to lookup annotations on persistent properties. This propagates into AuditingHandler and IsNewAwareAuditingHandler getting new constructors taking a MappingContext to set themselves up correctly. This will probably need store specific updates in the setup of the auditing infrastructure for namespace implementations and annotation based JavaConfig.

Introduced ….getPersistentProperty(Class<? extends Annotation> annotationType) on PersistentEntity to be able to access properties with a given annotation.

Updated SonarGraph architecture description and moved auditing related config classes into auditing.config package.
