    toaster: add rev dep column to image detail pages
    
    Add a column to the custom image pages that shows the reverse
    dependencies in a format matching the dependencies column:
      - either blank or a button showing the count of reverse dependencies,
      - when the button is clicked, a popover appears showing the list
        of reverse dependencies, with each package's size, and the total
        size of all of the reverse dependencies.
    
    The implementation adds a packages table method to retreive the reverse
    dependency total size, and adds a separate 'popover' html template. Both
    of these changes follow the pattern for the dependencies column.
