feat: Sentry integration for autoendpoint (#196)

* Update sentry to 0.19

* Override status_code() in ApiError's ResponseError impl

* Use the default Sentry transport and work around a Sentry issue

Working around this issue by using the `debug-logs` feature:
getsentry/sentry-rust#237

* Add custom Sentry middleware

Closes #155
