    collection-toolbar: Introduce the box creation popover
    
    This popover now just has a single option: "Create a virtual machine",
    but it is going to get new entries in this series with the introduction
    of the Remote Connection assistant, a new dialog which is decoupled
    from the existing wizard (that is going to be left only for virtual
    machines).
    
    Related to #306
