feat: Introduce Disable Collection

[A-Behairi]

By assigning a collection to the newly introduced Disable option in the indicator configuration a "disable" role will be added to the collection link on the indicator.
E.g config:

...

Collections:
  - E10a2_agricultural_production_area
  - E10a3_agricultural_production_area_change
  - E10a1_agricultural_production_productive_area
  - E10a9_agricultural_workers
  - E10a5_fruit_production
  - E10a6_harvested_parcels_evolution
  - E10a10_harvesting_evolution_winter_cereal
  - E10a10_2_harvesting_evolution_winter_rapeseed
  - E10a8_winter_cereals

Disable:
  - E10a3_agricultural_production_area_change

the corresponding indicator link:

{
      "rel": "child",
      "href": "./agricultural_production_area_change/collection.json",
      "type": "application/json",
      "roles": [
        "disable"
      ],
     ... 
    },
