Add auto extraction of Tor Exit Nodes

See how we extract them from IntelOwl.

I also think that the IP addresses detected as Tor Exit Nodes should be filtered by default, like we do right now for "mass scanners"

Greetings @mlodic. Very sorry for the inconvenience I cause a day before with my PR. I wasn't fully educated about guidelines, but now I will try my best to follow all the rules. Can you please assign this issue to me. ThankYou.
