Improved bugsnag reporting

- Include release stage, which should be 'production' or 'development',
  and gets postfixed by '-debug' when running in debug mode.
- Properly logging remote IP address when proxied through HAProxy;
- Log user ID, email, username, roles, and capabilities;
- Remove authentication tokens from logged session;
- Log request data and JSON separately.
- Added request endpoint.
