/**
 * 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.
