This adds bugfixed `fedora` element version to build from Cloud image
which implements fixes from this series ofchanges [1]

The ultimate goal is to be able to leverage fixes before they're getting
available through new DIB release.

+Use Fedora cloud images as the baseline for built disk images. For further
+details see the redhat-common README.
+
+Releases
+--------
+
+This element targets the current and previous version of Fedora; these
+values clearly changes over time.  To fix the version set the
+`DIB_RELEASE` variable to the Fedora version (e.g. ``36``).  The
+default value is the current best supported version (i.e. it may
+change upward at any given release to support the next Fedora).
+
+
+Environment Variables
+---------------------
+
+DIB_DISTRIBUTION_MIRROR:
+   :Required: No
+   :Default: None
+   :Description: To use a Fedora Yum mirror, set this variable to the mirror URL
+                 before running bin/disk-image-create. This URL should point to
+                 the directory containing the ``releases/updates/development``
+                 and ``extras`` directories.
+   :Example: ``DIB\_DISTRIBUTION\_MIRROR=http://download.fedoraproject.org/pub/fedora/linux``
