docs: Registers a BeanNameAutoProxyCreator class that wraps the bean being
  monitored. The proxy is associated with the PerformanceMonitorInterceptor
  for the bean, which is created when parsing the methods attribute from
  the springconfiguration xml file.
  
  @param source An Attribute node from the spring configuration
  @param holder A container for the beans I will create
  @param context the context currently parsing my spring config
