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__.

Default to only having cloud-init query Ec2 on first boot for Ubuntu,
until cloud-init has been SRU'd to fix the CloudSigma data source issue
that causes Trusty boots to hang.

Partial-bug: #1316475
The dynamic kernel module system is not available on RHEL, CentOS,
Scientific Linux, or SUSE. Make it part of the distro post-install
rather then base post-install.

The fedora element downloads images too, so we should re-use the caching
code from the ubuntu element.
There doesn't seem to be other examples of code shared between root.d
scripts. In the fedora and dpkg elements we copy install-packages into
the chroot, but that model doesn't apply when we're running scripts
outside of the chroot. Seems sane to just run it directly from the bin/
dir in the temporary hooks directory.

Also modified dib-run-parts to apply a more workable solution for
filtering out unwanted files such as editor backups and VCS.
The script is installed in its own element, depended on by the OS
specific ubuntu element. This is because the ubuntu element (and
later other OS's) are responsible for populating the root filesystem.
If we try to install this in base, the root filesystem will look to
be populated already and we will skip automatically choosing ubuntu.

This includes the install-packages implementation for dpkg, apt http proxy
config, daemon blocking and unblocking.
