sparkles: enhancements (#263)

* 🎨 Do not need to prefix '.' on queries

* ✨ Add recovery to stateapi

* ✨ Add cloudconfig SDK

* ✨ Unify post-install/firstboot hooks

This also adds capabilities to add grub option at first boot rather than
after installation as for bundles.

* 🤖 Optimize tests to wait for state to change
