Ian Wienand a44b55ccaa Turn down yum install-packages 
When debugging, this is very noisy for very little value.  If we need
to specifically debug this script we can turn up the level.

yum

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.

Custom yum repository configurations can also be applied by defining DIB_YUM_REPO_CONF to a space separated list of repo configuration files. The files will be copied to /etc/yum.repos.d/ during the image build, and then removed at the end of the build. Each repo file should be named differently to avoid a filename collision.
