Application Insights Instrumentation Key needs to be handled separately

[pratapladhani]

Power Apps Canvas apps allow adding an Application Insights instrumentation key as per this article.

After unpacking, currently this Instrumentation Key is part of the CanvasManifest.json file as part of the Properties Array. It would be great to have this Instrumentation Key pulled out as a separate file, so that it can be easily changed as part of the ALM CI/CD pipelines.

The fix here is to split the key into its own file to make it more accessible to ALM tooling. We'll call the file AppInsightsKey.json,

{
   "InstrumentationKey" : "ABCD"
}

Also need to verify there's no other changes to the msapp the app when a key is set.
