yum-minimal : update mirrors for Centos 8 The repo format has slightly changed for CentOS 8 (s/os/baseos/). Make the chroot builder look for a more specific repos.d directory first named for the distro variable, then fall back to to top-level dir (this avoids having to constantly change fedora). Update the gate mirror setup and roles for new Centos 8 paths too. Change-Id: I5b7f0c3624cac1d7aa7ed8bf6286b85d808b9c9a

Create a minimal image based on CentOS
Add minimal ubuntu and centos base elements There are times when a much more stripped down base image is desired over the distro cloud images. For instance, Infra would like some base images that do not have cloud-init or really much of anything else. This is easy to accomplish with debootstrap and rinse.

Port centos-minimal to yum-minimal Now that we have a generic yum-minimal element, just use it in centos instead of rinse. Adding base as an element-provides of yum-minimal because this element conflicts with the base element.

Use of this element will require 'yum' and 'yum-utils' to be installed on
Ubuntu and Debian. Nothing additional is needed on Fedora or CentOS.

CentOS 8 minimal testing and support This adds CentOS 8 into functional and boot tests. This completes centos-minimal support, documentation is updated and a release note is added. Change-Id: I435c2967b4f49faeb6d6edf189907b9f96e80357

By default this builds CentOS 7 images. Set ``DIB_RELEASE`` to ``7``
or ``8`` to explicitly select the release.
Fix networking for CentOS 8 By default network-scripts package isn't installed, so the directories for these files don't exist either. Skip by default for Centos 8. Change-Id: I194ec3735e17f27e586386541dc51f775b01e510

For CentOS 7, by default, ``DIB_YUM_MINIMAL_CREATE_INTERFACES`` is set
to enable the creation of
``/etc/sysconfig/network-scripts/ifcfg-eth[0|1]`` scripts to enable
DHCP on the ``eth0`` & ``eth1`` interfaces. If you do not have these
interfaces, or if you are using something else to setup the network
such as cloud-init, glean or network-manager, you would want to set
this to ``0``. For CentOS 8, this is set to ``0`` by default as the
system uses NetworkManager by default.
