provide a way for wizards on central to show up even if their plugin are not available

Provide a mechanism in Central to declare a wizard with icon, description etc. that can show up even without the required plugin is available.

If the plugin is available the wizard just start/works as expected.

If the plugin is not available user should be explained what needs to be installed and ask if they want it. Then attempt to install via the provided IU's and/or central connector id, ask for restart and once restart is completed and central is started again and the plugin is available - open dialog saying "You started XYZ Wizard - it is now installed. Want to start it ?"

If the plugin still is not available that is an error situation and should be told to the user.
