doing less.

To wire this registered cluster into a `TestClusterAware` task (e.g. `RestIntegTest`) you can resolve the actual cluster from the provider instance:

    tasks.register('someClusterTest', RestIntegTestTask) {
        useCluster someClusterProvider
        nonInputProperties.systemProperty 'tests.leader_host', "${-> someClusterProvider.get().getAllHttpSocketURI().get(0)}"
    }

#### Adding additional integration tests

                .getExtensions()
                .getByName(TestClustersPlugin.EXTENSION_NAME);
            ElasticsearchCluster cluster = testClusters.maybeCreate(restIntegTestTask.getName());
            restIntegTestTask.useCluster(cluster);
            restIntegTestTask.include("**/*IT.class");
            restIntegTestTask.systemProperty("tests.rest.load_packaged", Boolean.FALSE.toString());
            if (systemProperty(TESTS_REST_CLUSTER) == null) {
