* More on issue #54; watch for openstack experiments and try to download
  the new openstack stats file via the fast XMLRPC path. Show this as a
  text blob in a new tab on the status page, still need to graph the data.
  The apt_daemon handles the periodic request for the data (every 10
  minutes), which we store in the apt_instances table.

* Addition for Rob on the admin extend page; Add a "more info" button that
  sends the contents of the text box as an email message requesting more
  info and stores that in the ongoing interaction log. Responses from the
  user are not stored though, might look at that someday.

* Another addition for Rob; on the extensions list page, also show expired,
  locked down experiments. Note the sorting; at the top of the list are
  actual extension request (status='ready') while the bottom of the list
  are status='expired'.

* Add a "graphs" tab to the status page, which shows the same idle stats
  graphs that were added to the admin extend page. Most of this change is
  refactoring the code and sharing it between the two pages.
