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.
