A couple of bugs showed up with the graphical desktop images
(Workstation and KDE) for Fedora 24. Setting graphical.target
as the default by doing the symlink during image build, in the
virt-builder appliance, leaves it incorrectly labelled; in F24
this seems to stop systemd from reading it, so it falls back
to rescue.target when createhdds boots the image to try and
get the selinux autorelabel done, and relabelling never happens.
So instead, we change the default target with a firstboot
command (which will get run when createhdds boots to do the
relabel, so by the time openQA boots the image, the target will
be changed).
Also, a tricky bug in fedora-release has the ultimate effect
that if you start with a minimal install then install a desktop
environment on top - like we effectively do for these images -
the login manager service for the desktop does not get enabled,
as it should. So we work around that by explicitly enabling the
appropriate service with (again) a firstboot command.
Pushing without review as garretraziel is out this week and we
need these fixes - without them disk image generation in prod
is broken, which breaks quite a lot of tests.
Summary:
This goes with D839. It makes the necessary changes to report
the results for the desktop-terminal tests, and changes the
username in the upgrade test disk images from 'ejohn' to 'test'
to be in line with the name used in all the other tests, and
save us having to change the 'user_logged_in' needles.
Test Plan:
Run with D839, check that all tests work and results
are correctly sent to the wiki.

Summary:
createhdds.sh was just too damn simple and understandable, so
I thought I'd make it three times longer, object oriented,
and hard to understand!
OK, OK, that's not great sales. Alright. The main thing was to
make it smarter. This rewrite lets it do these things:
* Only create the images that are missing (not rebuild all)
* Work out the releases to build images for
* Rename images when appropriate
* Rebuild images when they need rebuilding
* Remove old / abandoned images
It can figure out what images ought to be present - including
working out the 'next' release and figuring out from that what
releases it needs images for - and build only the missing ones.
There's a 'version' concept for images; if the existing image
is older than the version given in the data file, it'll be
rebuilt. The data file can list 'rename' pairs, allowing images
to be renamed (like when we move from a single image to multiple
label/filesystem variants). This code uses fedfind's ability
to find the current release version to figure out what releases
we need virtbuilder images for (so you don't have to pass it
in). And it can find image files that aren't in the 'currently
expected' set and wipe them. Images can also have a 'maxage',
triggering a rebuild when they exceed it - this is intended
for the virtbuilder images, so we get a rebuild with the
latest updates every so often (default is two weeks).
The point of all this is to help with unattended deployment/
maintenance, i.e. the ansible deployment we have in infra;
the idea is that we can just set that up to run the 'all'
subcommand every so often, and it'll remove old images, create
new ones, and rebuild ones that are outdated.
I kept the ability to build a single image (or a whole image
'group'), and included the ability to just run a check without
actually doing a rebuild. There's a few little weird things
and holes here as it's not really the focus of the tool.
Test Plan:
Build all images, do a full test run, and see if
it works OK. Test out all the variations of building single
images / image groups, and using the 'check' command.
