Iustin Pop 8509e55b78 Improve check_dns command when used with monitoring-plugins 2.3
Version 2.3 of monitoring plugins did two things:

- change how multiple addresses are expected; no longer a single
  argument, with comma separated values, but repeated "-a" argument;
  sadly this is incompatible change, and configs need to be changed
  manually; this is commit
  monitoring-plugins/monitoring-plugins@a03068743f;
- add a "-L" argument that requires all passed addresses to be
  matched, which allows for stronger validation (all vs. at least
  one); this is commit
  monitoring-plugins/monitoring-plugins@fd9a7d2e00;

Both of these were committed a long while ago (2018), but were only
released very recently, in the 2.3 release (December 2020).

I've tried to make the descriptions as good as I could, but not sure
they're very readable, feedback welcome.
