Add WMI set capability

[Gijsreyn]

PR Summary

This PR adds the set capability on the WMI adapter #475. Traditionally, resources should have set, but in the case of WMI resources, it requires a method name and optionally parameters. These are filtered out during a Get operation, but canonical during a Set.

@Gijsreyn I appreciate your attempt here, but I think the problem is more complex. Some WMI classes actually support set like Win32_Environment (and gets even more complex due to Create or Update) and others like Win32_NetworkAdapter has a method SetPowerState() to power cycle it. I don't think it's worth trying to abstract this as it requires a knowledge base somewhere. Instead, it may make sense to have a different resource like Microsoft.Windows.WMI/MethodInvocation that takes a namespace, classname, method, and parameters and have set just try to call the WMI/CIM set operation.

Thanks @SteveL-MSFT. If you want me to hit that one up, let me know. Before doing so, let's have a quick talk on the design on the thing.

@Gijsreyn let's queue this up for next WG meeting

[Gijsreyn]

It was more work than expected @SteveL-MSFT, but as discussed during WG meeting, I have implemented the Set method. There have been some changes to the function to support both create/update. That's the reason some logic is moved to functions.

Probably in the documentation, we can make a note that it does not apply to CimClassMethods and static methods. I would appreciate it if you got time to do a review :)

Should be good to go @SteveL-MSFT . Hope this can be merged in before the preview release :)
