Devfile attribute is not propagated

[l0rd]

Describe the bug

The attribute controller.devfile.io/scc: container-build (used in this devfile for example) is not added in the corresponding DevWorkspace CR.

Note that this attribute is required to be able to run rootless build using buildah.

Steps to reproduce

• Use this devfile to start a workspaces
• The corresponding DevWorkspace doesn't have the scc attribute:

$ k get dw tilt-n-quarkus -o json | jq '.spec.template.attributes'
{
  "controller.devfile.io/storage-type": "ephemeral"
}

Expected behavior

I would expect that every attribute would be propagated, even attributes that are not known by Che.

As a "workaround"

# wait the workspace to start and then...
k patch dw <dwname> \
    --type='merge' \
    -p '{"spec":{"template":{"attributes":{"controller.devfile.io/scc": "container-build"}}}}'
