Subject: [PATCH] node/wire: manage logs for error establishing connection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of logging all IO errors as an error, match on the kind of the
error, logging an info message, otherwise an error.

These errors are informational, and cannot necessarily be resolved by
the node operator – since it is a matter of not being able to connect
to another end.
