* Based on `ssf-formula` (v0.3.0)
- https://github.com/myii/ssf-formula/pull/5
* Unable to use `pillar.example` directly for testing
- Used it as a basis for `test/salt/pillar/default.sls`
- Brought useful changes back to `pillar.example`
* Fix: avoid `users/googleauth.sls` for `RedHat` & `Suse`
* Close#203
