Description
During the helm transformer feature I added helm chart access (classic). Currently, resource download would fail since we do not have ResourceRepository support for the helm access type.

We need to provide a ResourceRepository abstraction and register that in the plugin system to allow cli based resolution for classic helm chart resources.

Done Criteria

• Create a resource repository in helm bindings
• Register the new repository in the plugin system
• Drop/Replace the temporary interface in bindings/go/helm/interface.go and use repository.ResourceRepository
• Add tests with helm access in cli
• Test that download resource also works
• Make sure it works with a resource created by ocm v1
• After its merged, update the helm transformer to use the new resource repository
• Code has been reviewed by other team members
• Analysis of existing tests (Unit and Integration)
• Unit Tests created for new code or existing Unit Tests updated
• Integration Test Suite updated (includes deletion of existing unnecessary Integration Test and/or creation of new ones if required)
• Enduser Documentation updated (if applicable)
• Internal technical Documentation created/updated (if applicable)
• Successful demonstration in Review
