Create (md5|sha256) checksum files for images
In shade, we use both md5 and sha256 checksums to help validate the
integrity of an image. Rather then having nodepool do this each time
for every time, have diskimage-builder create these files when we
build the image.

We've added a flag (disabled by default) to toggle this functionality.

48daefb685 Use temp file for du calculations
Storing the du output in a variable seemed convenient, but I didn't
realise just how big it could get especially with things like infra
images -- there's something like 100MiB of text being stored in a bash
variable here.

Convert this to work with a temporary file

e49d347ba9 Generalize logic for skipping final image generation
Since the ironic-agent element builds the ramdisk and extracts the
kernel itself, there's no need to actually generate an image at the
end of the process.  Previously the unnecessary image was being
deleted, but this wastes a bunch of time compressing and converting
the image.  It's better to just not create the image at all.

This change adds a noop element called no-final-image that
disk-image-create looks for in the element list and, if found, will
cause it to skip the final image generation.  This is more flexible
than the previous ironic-agent-specific method that would have
required changes to disk-image-create for every element that wanted
to behave similarly.

Note that this cannot be done using an environment variable, because
element environments.d entries do not propagate out to
disk-image-create.  It also doesn't make sense as a user option
because it should be set by the element author, not the user.

88bf264fbb Don't create an ironic-agent image just to delete it
The ironic-agent element doesn't care about the final qcow2/raw/
whatever image the disk-image-create command normally creates, so
previously it was deleting it at the end of the process.  This is
a pretty significant waste of time when building those images, and
instead we can just skip creating the image when building
ironic-agent.

34efed027a Add PS4 to show file/function/line in debug output
For something fairly simple, I went back-and-forward with this a bit.

Firstly, I realise calling readlink constantly sucks.  Due to the way
we call dib and source various files, you end up with the source-file
from "caller" being usually a very ugly path including levels of "../"
indirection.  Cleaning this up to something canonical is the only sane
way to present it.

Because we evaluate _ps4() from a sub-shell in the PS4 string, there's
no way for it to do something like build a global in-memory cache in
an associative array or similar.  It could write out a temp file or
some other side-band method, but the overheads of managing this don't
seem any different to just calling readlink.  If anyone can think of a
bash-hack around this that doesn't involve a fork() I'm interested.

We could potentially strip some of the leading paths in the assumption
you know what they are; but it gets complex when things are split
across /usr/bin & /usr/lib and external elements, etc.  I thought
about arbitrarily shortening it (e.g. just take last 20 characters)
which gives you enough of an idea of the file, but looks a bit ugly.
Or we could just leave the file-name out all together and assume the
function name is unique enough; this also seemed a bit ugly.

Obviously it's a matter of taste in the output.  It is certainly
wider, but it also adds a lot of information.  It also makes it fairly
clear where there are things we can make less verbose,
e.g. I1e39822f218dc0322e2490a770f3dc867a55802c disables tracing in
run-parts which is just noise.  There's a few other frequently used
loops that we could disable tracing for by default to benefit
signal:noise.

tl;dr : take a look at the logs.  I think it is a step in the right
direction of making the logs more usable for debugging.

docker rm with sudo and docker images don't always have a /tmp so check
before unmounting it.

8c837409b8 Turn down tracing for source-repo cache
If you check logs like [1] it's literally thousands of lines of the
same thing over-and-over as the git caching happens.  It is basically
all just noise unless you're debugging it specifically.  Up this to
tracing level 2 ("-x -x") to see it.  Add a note in the help about
multiple flags, which has always been intended but not documented.

Image builds should continue to run with single "-x", but we could
probably greatly increase signal:noise ratio in the logs with a little
more judicial use of this to turn down some of the very noisy &
repetitive parts.

5b6716cee8 Use fstrim to prep the block device
This cuts the image size down alot, esspecially if there were lots of
small file deletes.

The fstrim utility is in the util-linux package and should be on
most all systems. fstrim also works with XFS, ext4, btrfs, etc
prodiving the kernel is new enough.

A reduction of 25% or more in size is common.

fa3c5e3056 Add image size report
In the common case of not specifying a size, we are already running
"du" over the image to figure out how big it is.  Leverage that by
saving it's output and displaying a pruned list of big files when
requested.

We add a flag to show a summarised option (files >10MiB) and another
to show full output, should you wish that level of detail.

"Invocation" documentation is updated (and formatted a little better
while we're here).

76a8d3704b Add --version option to disk-image-create
Being able to discover DIB's version from the command itself is
convenient. This patch adds a --version option to the disk-image-create
command, failing gracefully if diskimage-builder is not installed.

This adds an explicit dependency on pbr to the requirements since this
is required to run diskimage_builder/version.py outside of a test
environment.

This patch consciously chooses to only provide the long-form option
and no '-v' to allow for the future possibility that a '-v' might
indicate '--verbose' in the future.

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.

6337e6fe17 Fix issue with leaking /tmp/image.* directories
When building the ramdisk we don't cleanup the temporary
directories after ourselves. This leaves /tmp/image.* directories
mounted and /tmp/image.* directories on the system.

Also the ramdisk-functions duplicate, from what I can see,
the cleanup function from common-functions. So when a job

This patch does not prevent you from using the previous
DIB_INSTALLTYPE_ variables to customize the install type,
rather it just changes the default so you don't have to
set it so often when using things like packages.
