version 5.2.1

- threshold: fix crash when display is None (_format_display now falls
  back to default format string instead of calling None.format())
- threshold: shorten notification messages by stripping plugin-name prefix
  from metric_path (cpu_percent instead of cpu_monitor.cpu_percent)
- main: demote aiohttp.access log records from INFO to DEBUG
- udp: replace debug print with proper logger.info for new host sign-on
