fix(gossipsub): gracefully disable handler on stream errors

Browse Source 
Previously, we closed the entire connection upon receiving too many upgrade errors. This is unnecessarily aggressive. For example, an upgrade error may be caused by the remote dropping a stream during the initial handshake which is completely isolated from other protocols running on the same connection.

Instead of closing the connection, set `KeepAlive::No`.

Resolves: #3690.
