Discovery of DVMs and Application Handler relays via NIP-65

[mikedilger]

Simple addition to NIP-65 to allow DVMs and application handlers to be discovered without just probing random popular relays and hoping they published a 31990 there.

I agree with using 10002s for relay selections, but shouldn't the k tag go on the NIP 89 handler?

[mikedilger]

The point here is that I don't know what pubkeys I'm interested in. So I can't search for 10002 by pubkey. All I know is the kind I want handled. And if I have the kind and 10002 gives me the relays, then I can find 31990s that are relevant at those relays. So I need to filter by that kind before I even get to the 31990 events.

We have this 31989 discovery system where you find things shared by your friends. Maybe that is all we really need, maybe it is even a bad idea to find DVMs as I'm suggesting without any kind of way to know if they are bad actors or not.

@mikedilger take a look at this PR: #1728 I think it covers this use case more cleanly (at the cost of some migration of DVM listings)
