Support exception management with Airbrake+Errbit

With Errbit, you can set up your own server and host the information
regarding your exceptions there. You can also hire Airbrake's hosting
services or easily setup Errbit on Heroku.

We're still including the rollbar gem so we don't harm CONSUL users who
are using rollbar.

Note Errbit requires an old version of Airbrake which forced users to
configure the gem. So we're adding the current environtment to
`ignore_environments` when the project id isn't defined; this way the
application won't crash in this case.
