bug: wrong display_label when using an enum attribute

[wvandeun]

Component

API Server / GraphQL

Infrahub version

0.16.0

Current Behavior

When you defined display_labels that references an enum attribute, it renders the display_label as <attr_name>Enum.<variant>, where attr_name is the name of the attribute and variant is the value.

Expected Behavior

The display label should use the string version of the enum variant for the attribute that we defined in the schema.

Steps to Reproduce

• start an instance of Infrahub
• load the following schema

---
version: "1.0"
nodes:
  - name: Node
    namespace: Infra
    display_labels:
      - test__value
    attributes:
      - name: test
        kind: Text
        optional: false
        enum:
          - one
          - two

• create a InfraNode instance, pick one as the value for the test attribute
• execute the following graphql query

query {
  InfraNode {
    edges {
      node {
        display_label
      }
    }
  }
}

• the display_label will be rendered as TestEnum.ONE
