Minor Right now, the document info bars are hardcode in the nuxeo-document-info-bar element. This means that addons cannot contribute to it and must add code directly to this Web UI element, creating a dependency. We must create a new nuxeo-slot to contribute info bars to this element.
As a first use case, we have the cold storage info bar, which should as well be moved to the respective addon and be contributed instead to this new slot.
