log probe script stdout/stderr

[Gordon Bleux]

currently only the script exit code is captured and logged. for better insight and debugging i would like to have access to the script output; especially stderr, as it might contain hints as to why the probe failed.

i was thinking debug! for stdout and info! for stderr, as warning/error logs are reserved for actual application problems.

That’s definitely a good idea, I am open to PRs on this.
