Why you don't check in permanent_addresses too?

So far, the
add_known_addressmethod of the networking was meant to be used to inject addresses that are permanent. In other words, addresses for reserved nodes or bootnodes that the user has explicitly configured.However, Polkadot now uses this method to add the addresses reported by the authority-discovery system. In other words, addresses reported by the nodes themselves.
Before this PR, these addresses would never be purged. After this PR, addresses that fail to connect to someone will be removed and not tried again until they are re-added.
cc paritytech/polkadot-sdk#540
This PR is sub-optimal, so I don't think we should be closing paritytech/polkadot-sdk#540. I'm doing this change to try to quickly improve the situation with parachains.
Ideally, we would have a proper story for addresses management, including properly documenting the behaviour, and removing addresses for peers whose reputation drops to 0, but these are way bigger changes.
