As described in the referenced bug, the dependency solver in yum
doesn't handle weak dependencies well and in some cases, such as
Fedora 26, can end up choosing coreutils-single (the busybox-esque
single binary) instead of actual coreutils, which then causes problems
with conflicting packages later.

fedora/centos-minimal don't obey DIB_DISTRIBUTION_MIRROR currently. I
don't really want them too -- we want to be able to separate the
mirrors used during the build process from those embedded into the
final image. Add DIB_YUM_MINIMAL_BOOTSTRAP_REPOS which is a directory
with repo files to use during the install.
This introduces setup-gate-mirrors.sh which is intended to setup
repo/sources/whatever files in the openstack gate that point to the
local region mirror. It pulls the info from the mirror_info.sh script
on each CI node.
The openstack-ci-mirrors element is updated to export these variables.
elements are updated to depend on it. Tests are restored

Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).
The problem with this is that editable/development installs (pip -e)
do *not* install data_files. Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.
data_files is really the wrong thing to use for what are essentially
assets of the program. data_files install works well for things like
config-files, init.d files or dropping documentation files.
By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from. In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].
We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.
Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.
I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.
Unfortunately, this has to move to work with setuptools. You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.
[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do. Essentially for us it's returning
__file__.
