/**
 * The JMX "managed resource" that represents the configuration for the health of GemFire.
 * Basically, it provides the behavior of GemFireHealthConfigImpl, but does some JMX
 * stuff like registering beans with the agent.
 *
 * 
 *
 * Unlike other ManagedResources this class cannot simply subclass
 * GemFireHealthImpl because it instances are serialized and sent to other VMs. This is
 * problematic because the other VMs most likely do not have JMX classes like
 * ModelMBean on their classpaths. So, instead we delegate all of the
 * GemFireHealthConfig behavior to another object which IS serialized.
 *
 * @see GemFireHealthJmxImpl#createDistributedSystemHealthConfig
