[Deletion Modes] Implement Logic to Extract and Insert Associated Resources into Manifest CR associatedResources

[jeremyharisch]

Description

With the issue described in lifecycle-manager #1582, a new field called associatedResources is added to the Manifest Custom Resource. This change requires implementing logic to extract the list of managed resources from the ModuleTemplate and insert it into the manifest.spec. associatedResources .

The list of managed resources is an additional layer in the OCM specification. An example of this can be found in the implementation described in template-operator #200.

After implementing this logic, the Manifest CR should look like this:

[...]
spec:
  install:
    name: raw-manifest
    source:
      [...]
  remote: true
  resource:
    apiVersion: operator.kyma-project.io/v1alpha1
    kind: Sample
    metadata:
      name: sample-yaml
      namespace: kyma-system
    spec:
      resourceFilePath: ./module-data/yaml
  associatedResources: 
     - serverless.kyma-project.io/v1alpha2/functions
     - operator.kyma-project.io/v1alpha1/serverlesses
  version: 1.1.1

Reasons

• Provide logic to extract managed resources from ModuleTemplate OCM Layer
• Fill in manifest.spec. associatedResources list

Acceptance Criteria

• Kyma Reconciliation Loop:
  • Extract managed resources from OCM layer (ModuleTemplate)
  • While creating Manifest CRs insert extracted managed resources into the manifest.spec. associatedResources
• Cover newly introduced functions in Unit-Tests
• Cover new functionality of Kyma reconciliation loop in integration test
