STRUCT - Send PerfMon metrics to StackDriver.

This is a Windows service that sends Perfmon metrics to StackDriver.   It currently sends stats at the minimum interval lenth allowed by StackDriver The service can also read the selected metrics from a S3 file and will update when that file changes.


You should use a different version of ServiceStack.Text - otherwise folks will need a license to run this. https://github.com/ServiceStackV3/ServiceStackV3 talks about it - I believe ```3.9.71``` is free to use.
