Create a POC for VS Code extension telemetry

[RabebOthmani]

As the Kiota team, we want to have the ability to collect meaningful telemetry
So we can have insights and make data-driven decision

The first step is to explore how to use the telemetry extension on VS Code . Work on a POC and run it locally.

here is the documentation page for reference

Here is what we're trying to validate:

• what does the reporter provide by default?
• how much additional instrumentation do we require?

After some testing it doesn't seem to collect anything by default besides maybe crashes

I'll poke around next week with the API to try to log events.

After implementing telemetry manually here is what we get

Application insights looks like it's obfuscating any EUPI. I'm going to submit the pull request this way we'll start receiving telemetry from the next minor onwards. And @RabebOthmani can refine what information and metrics we want to build up.
