Undertow mod_cluster CLI: Control LBGroup: Enable Nodes, Disable Nodes, Stop Nodes

As a follow up to JBEAP-215, this bug report is a member of a series addressing crucial CLI management capabilities.

Control Load Balancing Groups

For any Load Balancing Group enabled environment, it is essential to be able to Enable Nodes, Disable Nodes and Stop Nodes. These actions will enable, disable and stop all contexts with all nodes present in a particular Load Balancing Group.

It is an equivalent of sending this MCMP message attributes (LB-GROUP-1 is an arbitrary example Load Balancing Group name):

• Enable Nodes Cmd=ENABLE-APP&Range=DOMAIN&Domain=LB-GROUP-1
• Disable Nodes Cmd=DISABLE-APP&Range=DOMAIN&Domain=LB-GROUP-1
• Stop Nodes Cmd=STOP-APP&Range=DOMAIN&Domain=LB-GROUP-1

Call to action

Enable user to carry out these actions via WildFly CLI.
