debci now supports status alerts

After some work, debci now supports showing a status alert view in its web UI. The view allows debci admins to get an overview of the alerts reported by debci.

Currently, the view only shows packages that have reported tmpfail statuses although it should encompass more in the future.

Below is a screenshot of the status alert view running on autopkgtest.ubuntu.com.
