Exception notifier integration

[Startouf]

Hey, I just realized there was a gem for the fail_safe component I had tried to implement myself...
I am wondering if it would be easy to integrate exception notifier, which already does report exceptions very well and is connected to various services like Slack.
In addition, exception_notifier does a good job of exporting controller environment and request information (not sure safely does that)

Also, my fail_safe had a config where it is possible to always raise exceptions (useful for dev environment), to change the raised exception to a different one

This could be added to Errbase as a notification library and use ExceptionNotifier.notify_exception(e).

Hey @Startouf, this has been added to Errbase master.
