Add a --options flag that allows disk-image-create to send custom
options to qemu-img calls. It is useful for forcing compat into
qemu-img created images.
Usage:
disk-image-create --qemu-img-options compat=0.10 base ubuntu

The script to find best kernel from image (used by vm
and baremetal element) is duplicated and is not in sync
with each other. Moving the code to img-functions as a
function will reduce duplicated code and make it reusable
in future.
Since img-functions is not accessible in chroot env,
kernel selection is being moved from finalise.d to
cleanup.d in the vm element.

Currently when dib-lint finds a problem it does something like:
echo "ERROR: Problem found"
rc=1
This is repetitive and error-prone since it's easy to forget to set
rc to actually fail the check. This change makes those two steps
a single function call.

With this change, dib-lint ensure elements do not use tab
indentation. The following files are checked:
- executable file
- .md file

If scripts are not set -e then errors can be ignored, causing more
confusing failures later.
Also adds an exclusion comment to the ramdisk init script since we
don't want that to exit on failure.

There are certain scripts (such as the ramdisk init script) that
need to ignore linting rules for one reason or another. This adds
support for exclusions via a comment in the file like:
"# dib-lint: disable=executable sete"
There should be no ", but I need those to prevent git from treating
that as a comment. This syntax is similar to the pylint exclusion
mechanism.
Exclusion support is added to the executable check, but not
the alphabetical ordering one because I can't imagine a reason we
would need to disable that, and I don't know that comments are
supported in those files anyway.

save_image is used to copy kernel and ramdisks out of the image, which
we will sometimes want to keep the source, and sometimes not. However
for the main image itself, the temp copy is never kept, so use mv
rather than cp and avoid the excess IO.

In fb246a02eb we introduced an
ext4 option to allow root filesystems to be resized up to 1PB.
This appears to cause an ext4 resize2fs bug in some images.
When the issue occurs an image will hit a kernel bug when
cloud-init runs the resize2fs command during first boot:
kernel BUG at fs/ext4/resize.c:409!
In this commit we add a new option for max-online-resize
which can be used if a really large root partition is
desirable.
The root cause of all this is really a design problem in
DIB/TripleO at the moment in that we shouldn't have to worry about the
max size of the root file system when creating our images. Ideally we'd
just mkfs on the root file system itself. Much more efficient,
avoids this problem altogether...
I think the best thing to do today to avoid this is make setting
max-online-resize an option in DIB. This will allow us to stick
to the (well tested) ext4 defaults for most cases, and if someone has
need for a large root filesystem they can easily bump the setting. This
may be temporary until we either fix the design... or the ext4 fix is
released.

With smaller base images, such as Debian, the padding value used to
size the root filesystem does not leave enough room for grub which is
installed after the filesystem is created.

Occasionally cloud-init fails to resize the disk on first boot, this is
occuring because the filesystem has only 10% free. Nudging the disk size
up a bit more should give us a little more headroom so this is less
likely to occur.
I havn't been able to find out what value ensures we wont hit this
problem but I can say for sure this fixes all casses of the problem I
have seen.

Adds an option for --image-size, which sets the DIB_IMAGE_SIZE
environment variable. Having the cli option makes disk-image-create
more consistent in that parameters are able to be specified via a flag
on the command line or an environment variable. Also, you may not be
able to remember all the environment variables that you can tweak, yet
--help will tell you about the cli parameters. Preserves the old
behavior as well where if DIB_IMAGE_SIZE is set in your environment, it
will be honored.

This commit refactors the python code in diskimage_builder slightly. This is
in preparation for a larger review that adds more functionality to the python
code, namely the ability to apply elements to the current system as opposed to
a chroot. Further, the refactorings can stand on their own for better clarity.
They include:
- renaming elements.py to element_dependencies.py. Adds clarity about the
purpose of this module.
- updating other code for this rename.
- move tests into a tests submodule.

Commit 0210be22ae introduced the
possibility of basename being called on an empty string. Because
that can happen in normal operation (such as an x86_64 kernel,
in which case the PAE check will find nothing), don't allow the
basename error to kill the script. Also ignore failures in the
second basename call so the proper error message is echoed.

In some scenarios, the required space in the tmpfs partition can be
larger (or smaller) than the default one, producing errors due to
the lack of enough space (or performance penalties for not using
tmpfs).
Using --min-tmpfs <size>, we can hint the working set size we'll need
and let dib choose to avoid or use tmpfs.

When compressing an image, this is done in the same dir where the raw
image resides, doubling the amount of space needed (scarce when
using tmpfs), and then it's moved to the .cache folder in disk.
Combining these two functions, we reduce the amount of space needed
in the tmpfs partition (when in use), and the compressed image is
created directly on the .cache folder disk, so there is no need to
move the compressed image after the process into disk.
