We were checking tho project_id but not the project_key. However, in our
example secrets file we actually include a project_id but not a
project_key, and so new CONSUL installations would crash in production
environments.
Although technically the application doesn't crash if no host is
defined, we're also ignoring the current environment if no host is
defined, since errbit/airbrake is unlikely to work in this scenario.
Since some people hosting errbit might be using it as an internal tool
with a self signed certificate, we need to patch Airbrake so it accepts
these certificates.
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.
