Azure Application Insights reporter

[DeLoachAero]

NOT an issue, just an FYI...

If anyone is interested, I've thrown together a Metrics.NET reporter to Azure AI here:

https://github.com/DeLoachAero/Metrics.NET.AzureApplicationInsights

It's more of an experiment for me, as I wanted to learn a bit more about Azure AI and the quickest way I knew to get some metrics in it was to take an already Metrics.NET-instrumented app and send the data to AI. The biggest challenge turned out to be how to reduce the rich metrics of Metrics.NET down to the sparse types available in Azure AI; in the end I had to write each of the histogram and meter values as separate metrics, for example, since I definitely wanted to allow for alerting on, say, the 1 minute aggregates.

Probably most useful to those who already have Metrics.NET in their code and want to extend their options to Azure AI with negligible code changes.
