switch from Cloud 3 to Cloud 4
move and rename vagrant-libvirt management network
drop a whole load of patches which have been merged into Cloud 4
make indentation of heredoc consistent with rest of file
crowbar_register --no-gpg-checks

crowbar_register accepts a new option --no-gpg-checks in Cloud 4.
We need it here because we're using unsigned media.
for now, inject CLOUD and DEPS isos from host
add missing set -e to provisioner scripts
ensure cloud_admin pattern is fully installed

otherwise the check in install-suse-cloud will fail.
work around https://bugzilla.novell.com/show_bug.cgi?id=895417
forward port 3000 specifically to 192.168.124.10

Probably not essential, but a bit cleaner.
move provisioning shell scripts to separate files
fix mounting of isos on boot
fix port forwarding by getting rid of old libvirt settings

libvirt.connect_via_ssh was causing the port forwarding ssh
command to use

  -o ProxyCommand="ssh 'localhost' -l 'root' nc %h %p"

and that was causing keep-alive timeouts which killed the tunnel with a
broken pipe write error.
WIP remove barclamp-provisioner-demo-repos.patch

Not yet sure if we can get away with dropping this.
drop product version number

This will reduce the number of renames we have to do in the future.
update from SP2 to SP3

I guess this was an artefact from an old kiwi template.
only install VirtualBox guest additions if they're there

In libvirt boxes, they will never be there, and even in VirtualBox boxes
they might not be since we can probably get away without them.
