Limitations
-----------
* The plugin version 1.0.0 provides coordination only for Agent Central service.
* The plugin version 1.0-1.0.0-1 provides coordination only for Agent Central service.
Alarm evaluator and Notification agent will be supported in the next plugin
version.
* The plugin works correctly only on clouds with odd numbers of controllers.
This requirement is mandatory because Redis needs an odd number of nodes to
choose the master successfully.
