In YANGTOOLS-1090 the config list checking was fixed.

But there is still a case where it produces a warning where it shouldn't: when the non-config list is added via an augment. See the attached yang model, this produces the following warning:

2020-09-01 16:50:29,742 INFO [org.broadband_forum.obbaa.netconf.api.parser.YangParserUtilTest.main()] list.AbstractListStatementSupport (AbstractListStatementSupport.java:137) - Configuration list (http://www.example.com/example2)values does not define any keys in violation of RFC7950 section 7.8.2. While this is fine with OpenDaylight, it can cause interoperability issues with other systems [defined at /home/verthezp/tmp/odlwarning/example2.yang:11:4]

Since this list is added to a container with config false, the warning should not be there.
