This implements stats for windows nodes in a new package, winstats. WinStats exports methods to get cadvisor like datastructures, however with windows specific metrics. WinStats only gets node level metrics and information, container stats will go via the CRI. This enables the use of the summary api to get metrics for windows nodes.
