Undertow mod_cluster CLI: Control Node: Enable Contexts, Disable Contexts, Stop Contexts

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

Control Nodes

For any Undertow mod_cluster proxy environment, it is essential to be able to Enable Contexts, Disable Contexts and Stop Contexts on a selected worker Node.

It is an equivalent of sending this MCMP message attributes (worker-2 is an arbitrary worker node's JVMRoute):

• Enable Contexts Cmd=ENABLE-APP&Range=NODE&JVMRoute=worker-2
• Disable Contexts Cmd=DISABLE-APP&Range=NODE&JVMRoute=worker-2
• Stop Contexts Cmd=STOP-APP&Range=NODE&JVMRoute=worker-2

Call to action

Enable user to carry out these actions via WildFly CLI.
