 * <pre>
 * AGENT_HEARTBEAT: When the QMF Console receives heartbeats from an Agent, an AGENT_HEARTBEAT WorkItem
 *                  is pushed onto the work-queue. The WorkItem's getParam() call returns a map which contains
 *                  a reference to the Console Agent instance. The reference is indexed from the map using
 *                  the key string "agent". There is no handle associated with this WorkItem.
 *
 *                  Note: the first heartbeat results in an AGENT_ADDED WorkItem for Agent not an AGENT_HEARTBEAT.
