Send Web Request action should not deem all 40x responses as problematic

I'm using Automation For Jira to GET from an external API. 

If this particular API responds with a 404, that tells me a resource does not (yet) exist, rather than something fatal having occurred.

Simply ceasing the automation workflow at the point a non-200 response is received is not always desirable. 

The ability to toggle whether the Web Request action stops or continues after a non-200 response would be most helpful here.

Cheers!
