/**
 * Provides an implementation of DistributionConfig that
 * is used at runtime by a {@link InternalDistributedSystem}. It allows
 * for dynamic reconfig of the app the owns it.
 * 
 * The attribute settor methods in this class all assume that they are
 * being called at runtime. If they are called from some other ConfigSource
 * then those calls should come through setAttributeObject and it will
 * set the attSourceMap to the correct source after these methods return.
