`close_old_findings` and `skip_duplicates` should be configurable for Users

[rfelber]

In the current implementation there are two configuration options hardcoded and not configurable for users. Would be great to make them configurable:

defectdojo-client-java/src/main/java/io/securecodebox/persistence/defectdojo/service/ImportScanService.java

Lines 113 to 115 in 073387c

	mvn.add("close_old_findings", "true");
	mvn.add("skip_duplicates", "false");
	mvn.add("test_type", String.valueOf(testType));

@rseedorff You should be able to overwrite these by setting the close_old_findings or skip_duplicates in the options MultiValueMap (the last param in the function).
The options map take precedent over these settings, they are merely the default values.

This is (like everything in the client) not documented :(
