How to check if open telemetry is enabled

[andykais]

I am adding custom telemetry data for the open telemetry tools, and one of the first things I need is the ability to optionally do extra telemetry reporting work. What is the standard way to check if open telemetry is enabled for a particular deno run? I need to statically know if open telemetry is enabled, so the best tool I have right now is

const OTEL_ENABLED = Deno.env.get('OTEL_DENO')

The downside here is that the user needs to enable env OTEL_DENO permissions. Ideally, there would just be a deno global for this. Something like Deno.otel.enabled
