Sentry, for a while can do [performance monitoring](https://docs.sentry.io/product/performance/getting-started/) as well 🎉 It would be nice to get collective.sentry help on that. Officially sentry supports [django](https://docs.sentry.io/platforms/python/guides/django/performance/), [flask](https://docs.sentry.io/platforms/python/guides/flask/performance/) and [pyramid](https://docs.sentry.io/platforms/python/guides/pyramid/performance/). We can use them as a reference to implement it here as well.
