Feature: Landscaper: Blueprint Resource in Referenced Component Version

[robertgraeff]

Understand the problem

The blueprint of an Installation is currently given by specifying:

• a component version
• and the name of a resource in this component version.

  componentDescriptor:
    ref:
      componentName: github.com/openmcp-project/landscaper-examples/guided-tour
      version: 1.0.0
  blueprint:
    ref:
      resourceName: blueprint

It should also be possible to specify:

• a component version
• and a resource in a referenced component version (possibly following a path of several references). One option would be: instead of a resourceName, also support to specify the blueprint resource in form of a uri cd://componentReferences/<REF_NAME_1>/.../componentReferences/<REF_NAME_N>/resources/<RESOURCE_NAME> (as for example in subinstallations).

  componentDescriptor:
    ref:
      componentName: github.com/gardener/landscaper-examples/guided-tour
      version: 1.0.0
  blueprint:
    ref:
      resourceURI: "cd://componentReferences/ref1/resources/blueprint"
