Optionally ignore errors

[hadley]

The claude API is pretty flaky so often returns a 500 when I'm trying to record an actual request. It would be useful to be able to opt-out of vcrs default error handling so that this doesn't get recorded.

As in retry until a non error response? Or something else?

And just let the error bubble up, so the user has to deal with it.
