service module : remove flag confugration from openbsd enable/disable service (#80628)

fixes #66434


* removed flag setting from enable/disable on openbsd
  service was changing permanent config on openbsd, which is not expected from the this module
* if in check mode, module should not stop at enable/disable
* simplify and clean up opensd service enable/disable
* does break for those that were using service for configuring flags

+bugfixes:
+  - service module, does not permanently configure flags flags on Openbsd when enabling/disabling a service.
+  - service module, enable/disable is not a exclusive action in checkmode anymore.
+breaking_changes:
+  - service module will not permanently configure variables/flags for openbsd when doing enable/disable operation anymore,
+    this module was never meant to do this type of work, just to manage the service state itself. A rcctl_config or similar
+    module should be created and used instead.
