Azure exporters will now emit a "heartbeat" metric every 15minutes. The payload is a simple customMetric telemetry with certain customDimensions filled in depending on the environment that the application is running in (azure web app, function, app, VM, AKS). For now, the only defined environments are web apps and functions apps.
We want the heartbeat metrics producer to be a singleton that is run if ANY of the exporters are instantiated, so we set it as a global variable with a locking mechanism. Heartbeat is also not configurable and cannot be turned off.
Also, due to the vast amount of threads running, added names to the workers so it'll be easier to identify which thread is for what purpose.
