Add excluded_exceptions that is compatible with 2.0

[mcfedr]

So, given that I'm sticking with 1.x for the moment, I have made this solution, and I thought I'd share it as it might be interesting to you. I'm probably going to be deploying this on my server now.

Basically, instead of changing how exclude works, I've added a new option, excluded_exceptions that works just like it does in 2.0, and how I need it to work, excluding all subclasses.

As a bonus might make upgrade path simpler for people as they can start using excluded_exceptions in 1.X

I would be fine with this, i'm not to sure about the name but don't have a better suggestion so 👍

@stayallive I figured as its been renamed in 2.0, lets use the same name, as it has the same functionality.

As 2.0 is still in development and there is time to make things well, if anyone has a better name for the option I'm open to suggestions. Please note that the name (excluded_exceptions) is the same for the Ruby SDK

Ah did not notice that, I think it's fine then 👍

(FYI: build failure not because this PR)

Great suggestion. Can we make the exclude option deprecated to explicit better that this is the upgrade path?

As for the name, I'm fine with it
