Undertow mod_cluster proxy: CLI does not display/control load balancing groups

      Thanks to a good foundation established in JBEAP-215, there is an elementary information about registered worker nodes available, e.g.

      /subsystem=undertow/configuration=filter/mod-cluster=modcluster:read-children-resources(child-type=balancer,recursive=true)
      {
          "outcome" => "success",
          "result" => {"mycluster" => {"node" => {
              "worker-2" => {"context" => {"/clusterbench" => {}}},
              "worker-1" => {"context" => {"/clusterbench" => {}}}
          }}}
      }
      

      One of the information that is missing is Load Balancing Group. This is a Blocker issue, because absence of Load Balancing Group display and control capabilities blocks:

      • customer scenarios with rolling upgrades
      • customer scenarios with heterogeneous deployments
      • customer scenarios with clustering migration
      • all test cases linked to Load Balancing Group functionality

      The Load Balancing Group functionality appears to be present, so this issue might be resolved with adding CLI operations.

      Note that the attribute "Domain" actually stands for "Load Balancing Group" and it is not related to "WildFly Domain".
