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 commits provides support to add certificate while
building the image using ironic-agent element. The
certificate can be CA certificate or self-signed certificate.
The certificate is set to the environment variable
'DIB_IPA_CERT' which in turn is used by the ironic-agent
element while building the image.

The ironic-agent element is created using the disk-image-create utility
(even being a ramdisk) and outputs a .vmlinuz file for the kernel
(different than the ramdisk-image-create which outputs a .kernel file
for the kernel). This is inconsistent and make scripting against the
diskimage-builder more complicated if one wants to support different
types of ramdisk.
This patch creates a hard link for the .vmlinuz file to a .kernel file
at the end of the process (to keep backward compatibility) and print a
deprecation message.

Closes-Bug: #1482606
Switch to using svc-map element for systemd based agent.
This allows both .deb and .rpm installs to share the
element for systemd based installs. There are not any
plans to package a .rpm package for upstart or sysv, so
these are left as is.

Closes-Bug: #1490584
This patch is reducing the size of the ramdisk image generated by the
ironic-agent element. It does remove extra packages (graphical stuff,
dev stuff, miscs, docs, etc...) and purges directories that are not
needed for a ramdisk (like /boot since it boots using an external
kernel)
Currently it was tested generating a Fedora 22 image and reduced the
size of the final image from 464 MB to 211MB compacted (54% decrease).
I was able to boot a VM with 1.3 GiB of ram instead of the previous 3 GiB
needed.

Adds support for Ubuntu and Debian to ironic-python-agent. This will
enable building ramdisk with Ubuntu and Debian as base OS.
Updated README to further clarify what the element does.
