Fence Configuration Support Settings

NOTE TO DEVELOPERS: This is NOT intended to be a place for configurable variables.
                    Please put new cfg into the config-default.yaml

This exists primarily as a legacy support for old configuration, but has been
repurposed to hold some info used when searching for a provided configuration variable.
