Checkmk Werk 13819: Update of Windows update checkplugin and rulespec

ID: 13819 Title: Update of Windows update checkplugin and rulespec Component: Setup Level: 1 Class: Bug fix Version: 2.2.0i1 The "WSUS (Windows Updates)" rulespec now enforces that both warning and critical levels have to be set. Existing configurations will be migrated automatically. If only a critical level have been set before, the warning level is set equal to the critical level. If only a warning level is set, the critical level is set to 1000 times the warning level. The checkplugin and rule for "Windows Updates" used to interpret a warn/crit level of 0 as do not check this. Now you can explicitely set "No Levels". The verbosity flag has been removed. If important updates are detected they are always shown in the service details.
