Use CAIDA AS2Org to augment or replace ipinfo.io ASNames

[stephen-soltesz]

The ipinfo asname data is 2 years old and statically bundled with the uuid-annotator.

CAIDA maintains an AS2Org database, updated quarterly. https://publicdata.caida.org/datasets/as-organizations/

The downloader could be updated to fetch updates to this file, the uuid-annotator could be updated to fetch the latest file (as it does with maxmind & routeviews) and use this source instead of the static ipinfo data.

Open questions:

• how different are these datasets? (i.e. is this a drop-in replacement?)
• depending, can we get updates from ipinfo?
