[JENKINS-49241] pipeline hangs if slave node momentarily disconnects

In the middle of a build on a Windows slave, the build hung for a day with this message:

```
Cannot contact starfire: java.io.IOException: remote file operation failed: D:\jenkins\workspace\spro-2017\protocols\windows\msvc-15.0-32b-native-release-static-win32\sourcebuildspace at hudson.remoting.Channel@​5f758b70:JNLP4-connect connection from starfire.blue.roguewave.com/10.68.9.64:63685: hudson.remoting.ChannelClosedException: channel is already closed
```

I had to terminate the build manually.
