Ian Wienand 6802cf7100 Run dib-run-parts out of /tmp 
The dib-run-parts element was copying our internal version of
dib-run-parts into /usr/local/bin to be used running scripts inside
the target chroot.  However, it never cleaned up after itself.  This
means all images were left with an unmanaged local install of
dib-run-parts.

This copies dib-run-parts into the hooks directory of the chroot and
runs it from there.  It is cleaned up automatically on the exit path.

The dib-run-parts element is no longer required and it has been
removed from all dependencies.  It is left with a deprecation notice
in the README.  For compatability we convert it to simply install
dib-utils.

Codesearch shows no users depending on this unintentional implicit
install.  Note os-refresh-config depends on dib-utils and thus will
have an explicitly installed version.

docker

Base element for creating images from docker containers.

This element is incomplete by itself, you'll want to add additional elements, such as dpkg or yum to get richer features. At its heart, this element simply exports a root tarball from a named docker container so that other diskimage-builder elements can build on top of it.

The variables DISTRO_NAME and DIB_RELEASE will be used to decide which docker image to pull, and are required for most other elements. Additionally, the DIB_DOCKER_IMAGE environment variable can be set in addition to DISTRO_NAME and DIB_RELEASE if a different docker image is desired.
