chore: use `semantic-release` cross-formula standard structure

- currently you're forced to define extra states if you opt to install nginx with passenger,
 if you want the same outcome for passenger and nginx installs with equivalent config
- passenger is an extra module on top of nginx, makes no sense to end up with less configuration by default

* Automated using `ssf-formula` (v0.1.0-rc.1)

tofs: include path pattern with defaults in docs

ci(kitchen+travis): modify matrix to include `develop` platform

* Use balanced matrix based on `template-formula` guidelines
