Add unknown expiring entries to tracked relay config
I'm about to remove from the dirauth configuration files relays from 2007 to 2015. It's a big list and most of them have little to no description. Before 2016-ish, the comments weren't standardized so most of those entries if not all were quite tedious to parse especially for the fingerprints.
As a result, I've created a big list of "Expiring-Unknown". If we get an alert, we'll be able to correlate them with the dirauth commits or/and the sometimes cryptic comments associated to it. It will be a best effort situation but I expect most of them we'll just let them join back except if we have a positive hit on the fingerprints ofc.
