Add logging and alerting for unexpected application restarts
If the app experiences a fatal error and crashes, Azure automatically restarts the app. However, there is no easy way to see in logs that his happened, nor is there a way to be alerted. When this happened in our app, the only record of the error was in the "eventlog.xml" in Kudu. We would like to see these events in App Insights such that we can build alerts around them and more easily discover them.
