HTTPError and HTTPValidationError Information

[cjnething]

Feature Request

As per a Slack discussion, I'd like to request a nice "@Property" for accessing code and msg for HTTPError and HTTPValidationError. It would also be nice to get some documentation on the code types.

Motivation

This would be helpful for parsing errors and handling them appropriately.

Thanks all!

Thanks @cjnething for the suggestion, this is definitely needed and we'll take a look at adding this. Hopefully in the coming week!
