Fedora: Add support for configuring Yum mirrors

Browse Source 
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.

Use Fedora cloud images as the baseline for built disk images.
If you wish to use a Fedora Yum mirror you can set DIB\_DISTRIBUTION\_MIRROR
before running bin/disk-image-create. Example:
DIB\_DISTRIBUTION\_MIRROR=http://download.fedoraproject.org/pub/fedora/linux
This URL should point to the directory containing the releases/updates/
development/and extras directories.
For further details see the redhat-common README.
