Sets the VLA settings of the given attribute on every listed GROUP product and propagates the attribute
down to their assigned VARIANT products. The bulk twin of

Variant Attribute Configuration Validation

Variant-defining attributes must be properly configured to be propagated to variants.
This error occurs when a variant level attribute is not configured to be propagated to its variants.

Attributes marked as definingAttributes, locked or mandatory require copy = true. The same set of
flags is applied to every listed product, so the rule is checked once against the request body.

If copy is set to false (or omitted), the configuration becomes inconsistent and the request is rejected
with HTTP 400 Bad Request.

The whole request is validated before anything is written. If any listed product does not exist, is not a
variant group or family product, or does not have the attribute assigned, the request is rejected and no
job is created.

The work then runs as a background job. Poll GET /async/status/{taskId} for its status; the task ID is
returned in the Resource-Id header and the Location header points at the status resource.
