Don't dump the stack when Rollbar cannot be reached

[micahbf]

I use a DNS-level blocker for ads and trackers. Because of this, api.rollbar.com does not resolve on my computer.

The issue is, whenever I trigger an error with the CLI, it dumps a huge, ugly Python stack trace. (See below).

It would be nice if the CLI would swallow errors raised from the error reporting service.

Additionally, it could be nice to make the error reporting opt-in, or at least opt-out-able.

Thanks for the feedback! I think these are both great ideas. I can't promise when we will have time to implement them, but I'd be happy to approve a pull request if you have time to put it together.

Thanks, but I'm not much of a python guy. Just swallowing the exceptions would be a big improvement though, right now it is fairly unpleasant to use.
