Consider using NLNOG LG as a BGP source

[teunvink]

Due to issues with the previous NLNOG RING LG, irrexplorer uses BGP.tools's BGP export. Now that we have a stable LG running on our own infra, we could consider using that. Or add support (if not available) for multiple BGP feeds if we consider that to be a benefit.

Quick and dirty solution:

bgpctl show rib best takes 2-3 minutes in order to create an export. Either this format or SSV would work. Writing some Perl to turn this into the expected format is trivial.

IRR Explorer expects Hits>=20 by default which is hard to emulate with a best path dump, but a full dump will be in the tens of gigabytes and seems not to successfully complete anyway. Even dumps of individual RIBs (enumarable via bgpctl show) take minutes for small ones.

Ideally we find a way to extract that full dump.
