I just saw in the trace output of a failure
> grep -o 'CentOS-.[^>]*GenericCloud-.[^>]*.qcow2'
> sort -r
> head -1
sort: fflush failed: 'standard output': Broken pipe
sort: write error
i.e. the "head -1" has exited after reading one line, but "sort -r"
still wants to write and thus has hit a pipe failure, and because we
run with "-o pipefail" this has halted the script.
This seems like it has been there more or less forever, maybe we just
got lucky hitting it now? Anyway, we can work around this by using a
process substitution and passing the output of this into head, this
way we won't hit a pipe failure.
I also updated the fedora path as it does the same thing.

Fedora cloud images have sub-releases in their filename. It is not
exacly clear how this is generated but we do know how we can determine
the greatest programatically.

This updates diskimage-builder to support current Fedora releases (27
and 28) and removes support for Fedora 26 which is EOL as of June
2018.

The URL we are using seems to have disappeared. Update this to
download.fedoraproject.org. The new URL requires a "subrelease" now,
add it, along with a note on where it comes from.

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__.
