Update make uninstall (#191)

* Update uninstall

- create and delete authorino-operator namespace (requied by make
  install-authorino)
- add make uninstall-authorino
- add make uninstall-cert-manager
- update make uninstall

* Refactor deployment commands to have `<action>` and `un<action>`
- `<action>` = runs deps + action itself; safe to run if deps already present
- `un<action>` = undo the action only
