This patch introduces a bash library (scripts/lib.sh) that concentrates common functions. This also enhances future additions of other OSes, making it more simple. Also, new variables were introduced in each distro config.sh in order to parameterise the creation of package manager config (dnf/yum, in this case). A fix to the resulting rootfs directory name (include OS name) is also fixed in this patch. Fixes #39 Fixes #34 Signed-off-by: Erick Cardona <erick.cardona.ruiz@intel.com>
