36b59c001c Standarise tracing for scripts
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.

0b86194216 Disable all interfaces on eni systems
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.

f6ba2aeaf4 set -e all the things
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.

0072a39b2b Small fixes for dhcp-all-interfaces
I3166951c6fbb2faec53ffc339edd2fd0c3512300 recently landed without two
fixes that I suggested, namely using rm -f rather than testing for
file existance, and a comment fix.

0a797c86de Remove cloudy interfaces in dhcp-all-interfaces
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.
