DATACMNS-989 - Polishing.

Introduced overload for CustomRepositoryImplementationDetector.detectCustomImplementation(…) to take a RepositoryConfiguration to simplify the invocation from the Spring container related client. Further simplification to unify invocations also from the CDI implementation to be done in 2.0.

Expose getExcludeFilter() on RepositoryConfiguration to not have to inspect the configuration source on clients.

Formatting and Javadoc. Missing license headers in newly created types.

Original pull request: #195.
