Enrich telemetry data with function publish info

- What publish method was used? - `zipdeploy`, `blob url`, etc
- What environment was it published to?
- Generic HTTP Status code for the deployment result - `5xx`, `200` etc for zipdeploy

Start by locating the telemetry instrumentation and the deployment paths for zipdeploy and blob URL publishing in the Azure Functions Core Tools. Trace how the environment and deployment result are available, then define telemetry coverage for the publish method, target environment, and generic HTTP status; done means these fields are recorded for the listed deployment outcomes.
