Add e2e support for setting `backend.id` (Policy, Workflow, GraphQL)

Description

Update Policy syntax and related logic according to the Delegated Storage proposal.

Syntax

• Breaking change:

  Before	After
  rules: - interface: path: cap.interface.database.postgresql.install revision: 0.1.0 # exact revision oneOf: - implementationConstraints: # (...)	interface: rules: # rules for Interfaces, now nested under `interface` - interface: path: cap.interface.database.postgresql.install revision: 0.1.0 # exact revision oneOf: - implementationConstraints: # (...)

• Enhancements:

  • TypeInstances policy:

  # ...
  
  typeInstance:
    rules:
      - typeRef:
          path: "cap.type.aws.auth.credentials"
          revision: "0.1.0" # optional
        backend:
          id: "00fd161c-01bd-47a6-9872-47490e11f996" # Vault backend storage
      - typeRef:
          path: "cap.type.aws.*" # for any Type reference starting with such prefix
        backend:
          id: "31bb8355-10d7-49ce-a739-4554d8a40b63" # AWS secrets manager
      - typeRef:
          path: "cap.*" # Any other Type reference
        backend:
          id: a36ed738-dfe7-45ec-acd1-8e44e8db893b
          description: "Default Capact PostgreSQL backend"

  if capact-outputTypeInstances[*].backend not specified, check default from Policy.

  # default - static
  capact-outputTypeInstances:
    - name: mattermost-config
      from: additional
      # no backend definition -> use default storage backend

  During render:

  typeInstances:
  - alias: helm-release
    attributes: []
    createdBy: default/act-l49vh-30c7a078-6a77-475c-94dd-7466f56447ce
    typeRef:
      path: cap.type.helm.chart.release
      revision: 0.1.0
    value: null
    backend:
      id: 3ef2e4ac-9070-4093-a3ce-142139fd4a16 # helm-release backend - resolved UUID based on the injected TypeInstance

  • Defaults: extracted to Add common TypeInstance injection #635

  • Override defaults:

  interface:
    rules:
      - interface:
          path: cap.interface.database.postgresql.install 
        oneOf:
          - implementationConstraints:
                # constraints to select Bitnami PostgreSQL installation, for example:
                path: cap.implementation.bitnami.postgresql.install
            inject:
              requiredTypeInstances:
                - id: b4cf15d2-79b1-45ee-9729-6b83289ecabc # Different TypeInstance of `cap.type.helm.storage` Type - it will be used instead of the one from `interface.rules.default.inject`
                  description: "Helm Release storage"         
  
    default: # properties applied to all rules above
      inject:
        requiredTypeInstances:
        - id: "3ef2e4ac-9070-4093-a3ce-142139fd4a16"
          description: "Helm storage (cap.type.helm.storage:0.1.0)"

Nest Interface Policy which allows us to extend the Policy later:

• Nest Interface Policy under the interface field #625
• Nest Interface Policy under interface field hub-manifests#55
• Nest Interface Policy under interface field website#107
• Update Policy syntax after refactor dashboard#25
