"Unable to resolve FunctionGroupTag" logs for non-Flex apps

[mathewc]

We're logging what seems to be an unnecessary Debug log for all SKUs from this HostMetrics code. Function Groups are only used by Flex Consumption currently.

Unable to resolve FunctionGroupTag, FUNCTIONS_TARGET_GROUP is null or empty.

These logs confused me recently when I was investigating a non Flex CRI.
