@Nullable
    default Boolean verboseSocketExceptions() {
        return null;
    }
Returns whether to log the socket exceptions which are mostly harmless. If enabled, the following
exceptions will be logged:
<ul>
  <li>{@link ClosedChannelException}</li>
  <li>{@link ClosedSessionException}</li>
  <li>{@link IOException} - 'Connection reset/closed/aborted by peer'</li>
  <li>'Broken pipe'</li>
  <li>{@link Http2Exception} - 'Stream closed'</li>
  <li>{@link SSLException} - 'SSLEngine closed already'</li>
</ul>

<p>It is recommended to keep this flag disabled, because it increases the amount of log messages for
the errors you usually do not have control over, e.g. unexpected socket disconnection due to network
or remote peer issues.</p>

<p>This flag is disabled by default.
Specify the {@code -Dcom.linecorp.armeria.verboseSocketExceptions=true} JVM option to enable it.</p>
