Updates the fedora element so that DIB_DISTRIBUTION_MIRROR can
be used to configure a custom Yum mirror on Fedora. This
implementation replaces the baseurl in each of the default
Fedora Yum .repo files so that a custom mirror URL/path
can be supplied. The URL should point to the directory
where the updates and release directories exist. Example:
http://download.fedoraproject.org/pub/fedora/linux
As part of this change we also remove any existing
metalink settings in the .repo files to cover the case
where an end user runs their own createrepo command
to create the mirror... which means your metadata won't match that
of the normal Fedora mirrors and your baseurl won't get used.

Adds the ability to set $DIB_LOCAL_IMAGE to use as the base cloud image
for a Fedora image build. There are many repetitve tasks that are done
every image build. With this change you can build an image with the
fedora and vm element and then reuse the resulting image as input to
future image builds. This greatly reduces future image build times.
For instance 99-up-to-date is already taking almost 2 minutes (even with
rpm downloads already cached) for Fedora 20, and is only going to keep
taking longer. By having a local up to date Fedora cloud image, this
time can be saved on each image build.
There is one minor change to support this in that /tmp/grub needs to get
cleaned up at the end of image builds so that the image can be reused.
Plus, there is no reason for it to stick around anyway. (didn't think
this was worth a seperate commit).

This switches $CLOUD_IMAGES and $RELEASE to the DIB_ namespace so
they will survive future changes to the sanitisation of the build
environment.
