Windows default config uses checks deprecated with 2.16

[julianbrost]

Just something that got noticed during final testing of the 2.16.0 release. Not a serious issue, so it doesn't need to jeopardize the release.

We deprecated the bundled Windows check_*.exe check plugins, but actually ship a default config (that probably every user is going to replace) that still uses them. Thus, if you install an Icinga 2.16.0 MSI and then just run icinga2.exe daemon without changing any configuration, you'll be greeted with deprecation warnings like the following:

[2026-04-22 15:09:36 -0000] warning/Checkable: CheckCommand 'disk-windows' used by 'jb-win!disk C:' (in C:\ProgramData\icinga2\etc\icinga2/conf.d/services.conf: 42:1-42:53) is DEPRECATED and will be removed in v2.18. Further uses of this check command won't be logged.

I can reproduce this on Windows Server 2012 R2, but only if I actually run icinga2.exe daemon myself. In the shell. On the default config. Why would I do that... 🤔

During IfW install, which btw erased our default config, I also saw only green logs in PowerShell. So, if you ask me whether this is a problem, I'd say:

Yes, but actually no.
