Return peers for bootstrap?

[samyfodil]

tau implements a protocol called seer, which listen on DNS, so resolution for thing like .tau. are done dynamically.

examples:

$ nslookup substrate.tau.8bit.ws
Server:		127.0.0.53
Address:	127.0.0.53#53

Non-authoritative answer:
Name:	substrate.tau.8bit.ws
Address: 104.225.12.37
Name:	substrate.tau.8bit.ws
Address: 104.225.8.109

and

$ nslookup patrick.tau.8bit.ws
Server:		127.0.0.53
Address:	127.0.0.53#53

Non-authoritative answer:
Name:	patrick.tau.8bit.ws
Address: 192.73.240.48
Name:	patrick.tau.8bit.ws
Address: 192.73.242.72

It is handled here https://github.com/taubyte/tau/blob/main/protocols/seer/dns.go#L195

What needs to be done, is add a case for peers so

$ nslookup peers.tau.<domain>

will return a few peers we can use to bootstrap.

To get peers you can use user the seer service Node. I suggest shuffling, the picking up top N.
What I would do is look at the address of the request, if it came from a public IP, we only return public IPs.
