better pihole role; change update_only and uninstall from variable to global tag; update accordingly dependent roles

@@ -15,9 +15,10 @@ This repository aims to handle most of the Unitoo basic/ standard configuration
 
 The examples for `Dockerfile.example` and `docker-compose.yml.example` are useful if you need a basic container to test your playbook with different systems (like Centos/ Ubuntu). Copy them and modify as needed :)
 
-## Global variables
+## Global tags
 
-- **update_only**: used in combination with some tags to skip installation phase o not needed and trigger the update phase only (for configurations as example)
+- **global.update_only**: skip installation/ first setup phase and trigger the update phase only (for configurations as example); each role needs to implement this.
+- **global.uninstall**: activate the uninstall phase for specified tags and targets
