On-Chain fullnode discovery and tooling

[sherry-x]

Build tooling to allow fullnode register their address on-chain, for discovery

[gregnazario]

This involves needing onchain discovery as well, which is a decently large task. There's pieces in the codebase in the aptos framework for it, just the discovery needs to be fixed and adjusted

[davidiw]

Might be worth brainstorming here a bit, what type of on-chain registering can we do?

• Each peer can register in their own account
• This can be emitted as an event
• We can have a query to an indexer return a random sampling of these (or even have a tool that does health checks on these)
• A peer can randomly connect to these until they find one that is healthy

Healthy:

• I have an upstream peer
• I have seen a blockchain update in the past 30 seconds

I worry since we don't have a notion of upstream or distance from validators we don't have a strong definition of healthy. We probably should expose a value of distance from validator in the status message.
