eca59b2e97 dpkg: local cache for .deb files
With this patch, /var/cache/apt/archives directory content is preserved.
The directory is actually a bind mount of the
~/.cache/image-create/apt/$DISTRO_NAME directory, much like what we do
for ccache.
You can use DIB_APT_LOCAL_CACHE=0 to disable this behavior.

This trivial change improve performance A LOT (>30%), even if a local
HTTP proxy because:
 - there is no need to copy again and again the same files
 - we avoid network latency

The patch has been tested with Debian and Ubuntu with every elements
from the tripleo-image-elements repository, the final size of the cache
directory is about 700MB per distribution subdirectory.

16be6d7ce0 set -u and -o pipefail everywhere
As with the previous similar changes, this is intended to catch
problems as they happen instead of ignoring them and continuing on
to potentially fail later.  Setting this on all existing scripts
will allow us to enforce use via Jenkins.

381ff6ab1d Fix set -eu and pipefail failures
Fixes problems found by set -eu and pipefail, including:
-Many unset variables
-Commands that can fail under normal circumstances, which breaks
with set -e.  This change swallows those expected errors to allow
our existing error code to handle them.
-The dkms element was not finding Fedora kernel versions correctly.
This may be an issue for other distros too, but since Fedora was
working fine without this functionality I only changed it to print
a warning message rather than failing the build when it happens.
-The ramdisk init script will not be set -eu because if it fails
the result is a kernel panic, which can be tricky to debug.
However, in testing with set -e a few failing commands were found
and have been fixed in this patch.

46a14ae0e6 Uses policy-rc.d to prevent dpkg starting daemons
Currently the dpkg element fakes start-stop-daemon, initctl and
invoke-rc.d to stop dpkg from starting a bunch of daemons in the
chroot. This is problematic when packages use service, start, stop or
restart commands.

This patch uses a policy-rc.d instead of faking invoke-rc.d to achieve
the same thing. This approach now aligns exactly with debootstrap.
Without this patch DIB runs on some debian distributions fail
when trying to umount the chroot loop device as there are daemons
running.

The log will now show "invoke-rc.d: policy-rc.d denied execution of
start." instead of "Warning: Fake invoke-rc.s called, doing nothing."

b9348447b9 Don't block the upstart daemon if it doesn't exist
Check if Upstart exists before blocking the daemon.  Not all dpkg based
OS's have Upstart installed so this should help increase compatibility.

7f77729ec5 Move the dpkg specific stuff to a dpkg element rather than being hardcoded.
This includes the install-packages implementation for dpkg, apt http proxy
config, daemon blocking and unblocking.
