Ian Wienand 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.

===========
apt-sources
===========


This element overrides the default sources.list.

For APT based systems, if your network connection is slow for the default
sources.list in the upstream cloud image, you can define `DIB_APT_SOURCES` with
your favorite sources.list to override it, before running devtest.sh.

The new sources.list will take effect at build time and run time.

If you want to use this element with tripleo-incubator scripts, set `NODE_DIST`
/ `SEED_DIB_EXTRA_ARGS` / `UNDERCLOUD_DIB_EXTRA_ARGS` /
`OVERCLOUD_CONTROL_DIB_EXTRA_ARGS` / `OVERCLOUD_COMPUTE_DIB_EXTRA_ARGS` to make
it take effect at the appropriate time.

For instance, before running devtest.sh:
    export `DIB_APT_SOURCES`=/etc/apt/sources.list
    export `NODE_DIST`="ubuntu apt-sources"
