Replace Facter WMI call layer with MI call layer instead

WMI doesn't exist on all platforms - the alternative is to use the MI APIs instead (or worst case, call to PowerShell and use Get-CimInstance -Query "")

This effort currently tracks both Facter 2.x for the ability to run specs against Puppet on Nano, and for 3.x, which is shipped version compatibility.

MI_Session_QueryInstances

This effort should not actually include rewriting existing facts that use WMI, which is covered in FACT-1396. This ticket is to track reworking our extensibility layer to not use WMI.
