calling PropertiesV2 as library consumer

[jkroepke]

The windows_exporter embeds Microsoft's hcsshim library to fetch container metrics.

Currently, only the legacy v1 call can be used by other programs, as they do not have access to the internal package. For example, in hcsshim, the relevant function is defined internally and not exposed for external use.

hcsshim/container.go

Lines 169 to 170 in e5c83a1

	// Statistics returns statistics for the container. This is a legacy v1 call
	func (container *container) Statistics() (Statistics, error) {

However, there is no v2 function available that supports the new functionality.

The v1 legacy call has some limitations: If containerd is used, network statistics are no longer available, and Host/Job Containers are not exposed.
