Improved WMI query bulding functionality
When creating WMI-based performance rules & unit monitors, provide the "triangle" button in order to be able to specify any of the workflow's target properties (or hosted) when building the WMI query. Queries running agents hosting multiple instances of a targeted class (ex.: Logical Disk) will require that we filter the WMI query using the "WHERE" clause. For example:
WHERE DeviceID = '$Target/Property[Type="MicrosoftWindowsLibrary!Microsoft.Windows.LogicalDevice"]/DeviceID$'
Note that the button is available when building Windows Performance-based workflows (Object & Instance fields).
