fastapi instrumentation: add possibility to exclude some routes

[guillaume-chervet]

Hi,
Thank you for that awesome lib 😊

Jaegger is crumbling under my logs because I have a “/health” route that is called every second on more than 20 services. Is it possible to add the possibility of excluding routes?

Idea exemple :

from opentelemetry.instrumentation.fastapi import FastAPIInstrumentor

@FastAPIInstrumentor.exclude()
@app.get("/health")
async def health():
    return {"status": "OK"}

Or

FastAPIInstrumentor.instrument_app(app, ["/health"])

This is a great catch. We have exclude_lists via EXCLUDE_LIST environment variables for a lot of instrumentations but FastAPI is not one of them =p.
