authority-discovery: Ignore multi-addresses without IP from DHT records

[lexnv]

Kusama has several authority-discovery records published without a proper mutlti-address format.

authority="CzHcp6nEsT4NJuAbf4yCS2J8KKYpvuAe63bkWrPWhjaaT6w" 
..
addresses={.., /p2p/12D3KooWFegWJubWCeJCbWpDEAwukQmXKaWTyRgRRZ8NNdzmuxSr, ..}

In the previous example, an multiaddress of form /p2p/12D3KooWFegWJubWCeJCbWpDEAwukQmXKaWTyRgRRZ8NNdzmuxSr cannot establish a connection to the authority.

This PR changes the following:

• publishing DHT records no longer includes multi addresses that are empty or just contain /p2p/[peer] format
• received DHT records are filtered in a similar manner
• litep2p and libp2p backends verify discovered external addresses before pushing them to other subcomponents

Next Steps

• versi-net burnin with detailed logs
• kusama nodes (litep2p + libp2p) to ensure the warnings are not excessive

Closes: #6518

In kusama we also receive addresses of form:

/ip4/198.244.230.235/p2p/12D3KooWGJnJ3eA71NPV1bmMys2UWXQgoesVVD9bmXhi8aGKgjQz

Have added extra checks to accommodate this 🙏

[lexnv]

Will downgrade to debug after more testing, here and below

[lexnv]

With this PR deployed, we receive the following warnings for adding addresses (only on Kusama validators):

sub-libp2p: couldn't add known address (/ip4/127.0.0.1/tcp/30333/p2p/12D3KooWRjoe4poRBkBtuJ5JJGYanS7PWTfPc8sN4zvQ3gFEfSP6) for PeerId("12D3KooWRjoe4poRBkBtuJ5JJGYanS7PWTfPc8sN4zvQ3gFEfSP6"), unsupported transport

All warnings coming from this are related to addresses pointing to the localhost.

Will let this deployment run for a bit and then I believe its safe to turn these into debug

Would love another look over this 🙏

Just cross-checking if the following is intended:
ensure_peer_id modifies multiaddr, but the new value (which may contain p2p part) may get skipped.

[lexnv]

Yep, unfortunately libp2p API forces us to pass the event with a reference to the multiaddr (&'a multiaddr). I think this should be fine as long as we validate the address here. We also re-add /p2p/[peer] in the authority-discovery where this matters in publishing records 🤔
