The condor_configd daemon:
- Part of the configuration_tools git repo
- Provides a configuration file (99configd.config) that can be dropped into LOCAL_CONFIG_DIR
- The configd configuration defines LOCAL_CONFIG_FILE
- The configd augments existing configuration, but is authoritative for DAEMON_LIST
- Needs to know the location of the AMQP broker that is communicating with wallaby (QMF_BROKER_HOST)

Setting up a node with the configd daemon:
- Install the configd on each condor node to be managed
- Ensure the 99configd.config is place in LOCAL_CONFIG_DIR
