As the doc says, we want to remove all interfaces that come by default
in cloud images. Cloud images also come with an eth1 though, so lets
just remove all interfaces.

There is a wide variety of tracing options through the various shell
scripts. Some use "set -eux", others explicity set xtrace and others
do nothing. There is a "-x" option to bin/disk-image-create but it
doesn't flow down to the many scripts it calls.
This adds a global integer variable set by disk-image-create
DIB_DEBUG_TRACE. All scripts have a stanza added to detect this and
turn on tracing. Any other tracing methods are rolled into this. So
the standard header is
---
if [ "${DIB_DEBUG_TRACE:-0}" -gt 0 ]; then
set -x
fi
set -eu
set -o pipefail
---
Multiple -x options can be specified to dib-create-image, which
increases the value of DIB_DEBUG_TRACE. If script authors feel their
script should only trace at higher levels, they should modify the
"-gt" value. If they feel it should trace by default, they can modify
the default value also.
Changes to pachset 16 : scripts which currently trace themselves by
default have retained this behaviour with DIB_DEBUG_TRACE defaulting
to "1". This was done by running [1] on patch set 15. See the thread
beginning at [2]
dib-lint is also updated to look for the variable being matched.

We are autodetecting and configuring devices in dhcp-all-interfaces
so having one configured in /etc/network/interfaces by default
is redundant and slows boot down.

Closes-Bug: #1239480
Using set -e in all of our scripts will prevent some subtle bugs
from slipping in, and will allow us to enforce use of set -e with
tooling.
This change also adds -u and set -o pipefail in the less complex
scripts where it is unlikely to cause problems. A follow-up change
will enable those options in the complex scripts so that if it
breaks something it can be reverted easily.

I3166951c6fbb2faec53ffc339edd2fd0c3512300 recently landed without two
fixes that I suggested, namely using rm -f rather than testing for
file existance, and a comment fix.

Moves the code that removes default cloud interfaces
into the dhcp-all-interfaces element. Having it live in
stable-interface-names won't work right now because we
need this for virtualized testing.
