Add ability to log all exceptions (#2262)

* Add ability to log all exceptions

* Fix linting 🙄

* Remove shorthand

* Make `ErrorHandler.log` backwards-compat

* Ignore mypy error

* Don't store `noisy_exceptions` attribute in app

* Added tests

* Store noisy exceptions setting in config

* Default to not-noisy if config key not available

* Add CLI tests for `noisy-exceptions`

* Remove debugging line I left in 😅

* Fix tests
