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__.

For some use cases, it can be useful to keep all the kernels
and not just keep the latest one. Add a parameter that allows
it, and continue cleaning up kernels by default.

As described in the comment, there is a dnf equivalent of this command
that doesn't require us installing yum-utils (which drags in yum on
dnf-only systems such as f23)
This is a small consequence to this -- due to us not installing
yum-utils some installs will now be completely yum free. This causes
a breakage in ironic-agent 99-remove-extra-packages where we remove
the yum package. There is a long-standing bug/feature where missing
packages in a group of packages do not cause yum/dnf to exit with
failure, but uninstalling a single package will. Because we have made
the systems yum-free, the uninstall of yum can fail in this corner
case.
It has always been like this, so I'm in favour of the "ain't broke"
approach. To work-around this, I have just put yum into the existing
list of packages to be cleaned up. I have added a note to the yum
installer taking note of this behaviour for future reference.

dib-run-parts filters the acceptable characters in script names,
and "." is not allowed (see $allowed_regex there), so
01-clean-old-kernels.sh is never executed.
Rename it to drop its .sh extension, so it is executed for real.
