FastAPI Instrumentor not populating attributes required for Azure exporter

[gautam-ergo]

Describe your environment

Package Version - azure-monitor-opentelemetry-exporter = {version = "^1.0.0-beta.3", allow-prereleases = true}
opentelemetry-instrumentation-fastapi = "^0.19b0"
Operating System - macOS Mojave v10.14.6
Python Version - v3.9.0

Steps to reproduce
When using the azure-monitor-opentelemetry-exporter in conjunction with opentelemetry-instrumentation-fastapi
the response code is not populated by the exporter, raised this issue with Azure monitor team and was redirected here;

Looking at the output, it seems like the spans are missing some attributes. This is probably an issue in the opentelemetry-instrumentation-asgi, could you file an issue here for this problem specifically? Basically, the exporter sees if http.status_code is populated in the span attributes to populate response_Code in app insights. Since the attribute is not there, this is why you are seeing 0s. Normally, it is up to the instrumentation to populate this.
