[RFE] Only scroll log viewer down automatically if the view is at the bottom of it

https://github.com/kinvolk/headlamp/blob/620e79d80c4330a0914ebbb6238b23e27b192efd/frontend/src/components/common/LogViewer.tsx#L62

  React.useEffect(() => {
    // @todo: Only scroll down automatically if the view hasn't been scrolled up by the user yet.
    if (logsBottomRef && logsBottomRef.current) {
      logsBottomRef.current.scrollIntoView();
    }
  }, [logs]);

Update (by Joaquim): This is about:

• [ ] By default the log viewer shows the logs as they happen, scrolling to the bottom automatically like a terminal view
• [ ] If the user scrolls the view up, even the tiniest bit, it should remain showing that portion of the log even if more logs arrive
• [ ] If the user scrolls down to the bottom again, then new updates will keep the view at the bottom (i.e. it will show the latest contents)

@fondoger , Not really, but if it's important we can raise its priority.
