docs: Add a new handler given the classname and config filename. It instantiates
  the class and then calls its initialization method to get the handler ready
  to process inbound probes.
  
  @param classname is the FQCN of the handler class
  @param configFilename is the full path name of the config file name
  specific for the handler (could be any crazy format)
  @throws ResponderConfigException if there is some issues with the config
  file
  @throws TransportConfigException if the transport configuration failed
