* HA-Singleton interface.
* Only one mbean is active at any point in time, cluster-wide.
* <p>
* The service provides a simple way for a concrete mbean to detect whether
* or not it is the active one in the cluster.
* <p>
* Concrete mbeans would usually do activities like regular clean up of database tables
* or saving statistics about cluster usage.
