Javier Pena f13eb1bcea Ensure yum-utils is installed in epel element
We are running yum-config-manager/dnf config-manager in the epel
element. Even though the yum-utils package is declared in the
package-installs.yaml file, the package-installs pre-install.d
script is executed after the one in the epel element, so image
build fails.

This commit ensures yum-utils or dnf-plugins-core are installed
before running the command.
