code: public List<KojiBuildInfo> listBuildsContaining( ArtifactRef artifactRef, KojiSessionInfo session )
                      throws KojiClientException
      {
          return computeIfAbsent( KOJI_BUILD_INFO_CONTAINING_ARTIFACT, ArtifactRef.class, List.class, artifactRef,
                                  () -> kojiClient.listBuildsContaining( artifactRef, session ),
                                  kojiConfig.getQueryCacheTimeoutHours() );
      }
docs: The caller actually passes SimpleArtifactRef which has right hashcode/equals so we can use it as cache key.
