James Slagle c9a6aef9f4 Add yum element.
The yum element provides for specific customizations
for yum based distros.  The included customization is
a yum cache mounted outside of the chroot so that yum
downloaded packages are reused on subsequent image builds.

Provide yum specific image building glue.
RHEL/Fedora/CentOS and other yum based distributions need specific yum
customizations.
Customizations include caching of downloaded yum packages outside of the build
chroot so that they can be reused by subsequent image builds. The cache
increases image building speed when building multiple images, especially on
slow connections. This is more effective than using an HTTP proxy as a yum
cache since the same rpm from different mirrors is often requested.
