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__.

This patch solves three issues with Debian packaging / apt:
o When building 'testing' only default apt sources is
included - backports, updates and security are skipped because they
do not exists.
o The default release for Debian was `unstable`: this is now fixed to
`stable`.
o Starting a Debian Stretch VM that was build with diskimage-builder
does not work, because some mandatory packages are missing.
This patch fixes this problem: it adds the mandatory packages and
the test case.

'locales' package gets installed before '12-debian-locale-gen' is executed
and generates effectively empty /etc/locales.gen in debian, which makes
dpkg-reconfigure call to locales ignore the values set by
debconf-set-selections.
* Remove /etc/locale.gen generated by 'locales' installation to ensure
proper locales generation on debian images
* Remove 'locales-all' package installation from debian element since
it's not needed anymore to build the image and cosnumes additional
~120MB of space
* Remove unused 'package-installs' dependency from debian-minimal
element

Closes-Bug: #1452400
debootstrap is not debian or ubuntu specific. We can make a debootstrap
element that knows how to do all of the things, and then a
debian-minimal and ubuntu-minimal image that use it. Finally, make
the debian element simply be a collection of the extra things we do to
make it look like a cloud-init based cloud image.
