This adds "openstack-ci-mirrors" element which performs various
settings to get builds using local mirrors. As a first step, we
convert ubuntu-minimal jobs
The main trick is that since infra mirrors are created with rerepo
they are not signed (they are recreated, not cloned, and not signing
is seen as a feature in that it deters external use). So we need to
instruct debootstrap to ignore signing and also turn it off for
in-chroot apt. Other than that, the existing DIB_DISTRIBUTION_MIRROR
works to redirect installs.
Remove "restricted" as it's not mirrored, and I don't think we want it
in here by default.
(I think DIB_DISTRIBUTION_MIRROR is a bit of an anti-pattern, because
it leaves the mirrors in the final image -- just because you use them
to build, doesn't mean you want them at runtime). But we don't need
to fix that now, and we don't use any created images.)
This pauses fedora testing until the next change, which moves to using
local mirrors for testing on fedora/centos

package-installs.yaml is installing python-dev, not python2-dev,
so we need to adjust the mapping accordingly.
In addition, zypper-minimal used an dpkg specific package name,
while there is a SUSE equivalent (and zypper-minimal is anyway
SUSE family specific)

If DIB_PYTHON_VERSION is < 3 on the !redhat path, that means we're on
an older platform that may not have python3-virtualenv packages. Skip
install.
Ensure the order of operations happens by forcing the installs
Also add a note about limited platform support (patches welcome :)

Recent changes in project-config have shown that we leave the system
in an inconsistent state when installing from source. On fedora, we
will have installed the python2 packages, but then used $DIB_PYTHON to
install python3 pip from source!
This tries to clarify the situation. As described in the document,
with package installs, we just install the $DIB_PYTHON packaged
versions.
Source installs want to take over the global namespace. This is the
price you pay for running the latest versions outside package managers
:) The only sane thing seems to be for us to normalise python2 &
python3 versions of pip, setuptools and virtualenv and then hacking
things such that "/usr/bin/pip" and "/usr/bin/virtalenv" remain
defaulted to python2 versions.
Documentation is added

Currently we install pip/virtualenv with "/usr/local/bin/dib-python".
This means that every time you create a virtualenv, the python
interpreter inside it is called "dib-python" which is confusing.
Add an env var DIB_PYTHON that points directly the to interpreter
available during build, for use when running scripts.

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__.
