Refactor to use job templates

 ## General tips
-* Use the `name` argument to use a component multiple times in a single CI/CD pipeline
-* Use a `name` stating with a dot and extend the job if you need more customization
+* The jobs in this CI component are job templates. This means, by default, all job names start with a dot.
+  This approach has two advantages: you can use the job to instantiate multiple jobs from the same template using `extends`,
+  placing conditions on jobs becomes easier and avoids cases when no job is scheduled.
+* Use the `name` argument to use a component directly without `extends`
