[Deletion Modes] Introduce associatedResources field to Manifest Spec

[nesmabadr]

Description

In order to support #1211, we need to have the associatedResources saved in the ManifestSpec.

Reasons

To support managed resources, we need the associatedResources field so that it can be used to determine which resources are managed and need to be deleted first from the SKR Cluster.

Acceptance Criteria

• Introduce optional AssociatedResources field to Manifest Spec
• Add corresponding Documentation

Example Manifest CR:

[...]
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
