This PR add support to create and manage "Collections" this will be the Terrakube equivalent for variables sets

There is a new teams permission called "manageCollection" that is require to create the "collection".

Create Collection

POST /api/v1/organization/${ORGANIZATION_ID}/collection/

{
    "data": {
        "type": "collection",
        "attributes": {
            "description": "Sample Description",
            "name": "Collection1",
            "priority": 10,
        }
}

Higher the number higher will be the priority

POST /api/v1/organization/${ORGANIZATION_ID}/collection/"${COLLECTION_ID}/item/

{
    "data": {
        "type": "item",

            "category": "ENV",
            "description": "random_description",
            "hcl": false,
            "key": "random_key",
            "sensitive": true
        }
}

The type could be Environment Variables or Terraform/Tofu Variables

    "data": {
        "type": "reference",

            "description": "my random description"
        },
        "relationships": {

                "data": {
                    "type": "workspace",
                    "id": "5ed411ca-7ab8-4d2f-b591-02d0d5788afc"
                }
            }
        }
