Make it possible to not send outgoing traffic to RFC1918 addresses

[fabricedesre]

This triggers abuse behavior detection from some hosting providers like Hetzner.

Can we add a flag in the p2p config for that if we don't want to block these addresses in all situations?

@dignifiedquire any idea where I should look at? I got a bit lost in the maze of libp2p events to figure out if we can have a say in which discovered multiaddr we want to actually connect to.

There are a couple of places where we could look, but to be sure we would need to filter all dials, including the ones happening in libp2p. I would suggest opening an issue on rust-libp2p asking how to avoid this, as I haven't found any API to do this. :/

I opened libp2p/rust-libp2p#3370

There's a promising solution in libp2p/rust-libp2p#3370 (comment)
