✏️ Editing: cobblersettings.aug

(*
    Parse the /etc/cobbler/settings file  which is in
    YAML 1.0 format.

The lens can handle the following contructs
    * key: value
    * key: "value"
    * key: 'value'
    * key: [value1, value2]
    * key:
       - value1
       - value2
    * key:
       key2: value1
       key3: value2
