[feature-request] Allow ignoring errors by Error type

[pedromss]

I noticed that out of the box Plugsnag reports 404 Phoenix.Router.NoRouteError errors. I would like to request a feature that allows not reporting based on status code exception. I can't see a use case for wanting to report 404 NoRouteError as a bugsnag because anything can trigger a 404 NoRouteError so if someone were to spam our system with routes we don't have we'd essentially be bleeding out Bugsnag quota.

From the docs, there didn't seem to be a way around this, I only say the custom error builder, but I might have missed something.

Let me know if you're open to this and if you'd like me to take a shot at it.

Hi, @pedromss

I've since moved to other providers so not actively using Bugsnag anymore.
I do think it makes sense and would welcome a PR!

Does it?

Are changes introduced in #40 not working?

You're correct, I made a mistake in the report. Its not a 404, its a NoRouteError error raised by Phoenix. I'll update the initial description to reflect that.

Hey @pedromss ,

NoRouteError is a 404 per https://github.com/phoenixframework/phoenix/blob/e99f657f1cc9062fca0f2b8b79bc90659d8bd514/lib/phoenix/router.ex#L6, right?

So, I guess my question

Are changes introduced in #40 not working?

still stands.
