Currently there is no description of dependencies in the generated
documentation of the elements: therefore a user of an element does not
know which other elements are automatically included and e.g. which
configuration options are available. In addition there are some
copy&pastes of parts of the README.rst scattered thought different
Ubuntu and Debian specific elements.
This patch adds a semi-automatic generation of dependency information
of all elements. Nevertheless these are not automatically included.
The author of the element's README.rst can decide if and where the
dependency information should appear and can use the descriptor
.. element_deps::
for this.
This patch adds the dependency information for some Debian and
Ubuntu patches - and creates the base for later removing the
duplicated parts.
A call is added to element_dependencies._find_all_elements() to
populate reverse dependencies for Element objects.

During the creation of a disk image (e.g. for a VM), there is the need
to create, setup, configure and afterwards detach some kind of storage
where the newly installed OS can be copied to or directly installed
in.
This patch implements partitioning handling.

Cleaning logs was split, some was done in the
img-functions.finalise_base, some was done in the base element.
The version unifies tidy up logs in the lib/img-functions.
Especially when building docker container images the base element
cannot be used. This patch removes about some hundreds KB of
useless logs in cases when the base element is not used.

Every run we are doing a full tar.gz of the chroot environment that
never gets used.
It's not suitable for CI since we use fresh images each time there.
The cache in general isn't really isn't a very safe thing to have
around, because there's no invalidation procedure and no real way to
make one -- we've no guarantee that a new chroot build even moments
after a previous one wouldn't bring in or different packages, etc (of
course this is *unlikely*, but the longer you go between builds the
worse the problem becomes. Also, tons of packages get installed after
this not from any cache, so potential speed-up is rather marginal.
Debian turned this off with I58fc485aacacaa17243bf9ce760ed91256d1f182.
However, given the reasons above and it's complete lack of testing, I
don't see this as useful.
If we really want this type of thing, I think we should come up with a
way to use a persistent external yum/dnf cache that yum/dnf keeps in
sync with it's usual invalidation rules.

Set the grub timeout to 5 seconds by default, and add notes on how to
update this. This will stop infra having to carry an element that
goes and rewrites the grub configuration.

The squashfs format brings a couple of advantages over the other
formats. Image is often an order of magnitude smaller and it can
be used natively, either as an initrd, either with loop mount.

Debootstrap only supports one apt repository to install packages from.
As a result, we do not consider the updates repo during debootstrap
causing us install a second kernel when we do an apt-get dist-upgrade
during build.
Lets use debootstrap to get us a minimal chroot, then add our repos and
install the correct packages from the start.
We also have to reorder the dpkg root.d scripts which configure apt so
they run before we perform our package installs.

Add new 'openssh-server' element to ensure that openssh server
is installed and enabled during boot. This is mostly useful for
*-minimal images which do not come with openssh installed and/or
enabled in order to keep a small dependency footprint.

Move dib-run-parts from dib-utils into diskimage-builder directly.
For calling outside the chroot, we provide a standard entry-point
script. However, as noted in the warning comment, the underlying
script is still copied directly into the chroot by the dib-run-parts
element. I believe this to be the KISS approach.
This removes the dependency on dib-utils. We have discussed this
previously and nobody seemed to think retiring dib-utils was going to
be an issue.
This also updates the documentation to not mention dib-utils, or using
disk-image-create via $PATH setup, but rather gives instructions on
installing from pip with a virtualenv.

Move managing of SSH host keys into a dedicated element.
Because glean doesn't generate SSH host keys anymore, we need to do it
with a systemd script. This is already handled by CentOS / Fedora so
we don't want to add it there.
This was done to address the upstream bug in debian:

Move element-info from a wrapper script to a standard entry-point
console_script.
Update the documentation to explain how to run it for development. I
don't think we should support the idea that you can check-out the code
and run ./bin/disk-image-create -- it has dependencies (dib-utils,
etc) and needs to be run from a virtualenv (this is what CI in the
gate does). A follow-up can clean-up some of the path munging stuff
we have for this in disk-image-create.

These new variables are a list of elements chosen for the build along
with their full paths. For Python elements, IMAGE_ELEMENT_YAML is a
YAML formatted list that can be easily parsed. For bash elements,
"get_image_element_array" will produce an associative-array of the
same (working around lack of array export in Bash).
This list is intended for consumption of elements who need to copy
files from other elements, such as pkg-map and svc-map. As discussed
in I2a29861c67de2d25c595cb35d850e92807d26ac6, this list has already
been pruned and had overrides processed, so it is safe to simply walk
over this list with no further processing.
Since we're presenting the element list in a couple of different ways,
we combine it all into the element-info script. It will output an
eval-able string that declares the appropriate variables.
I've added some inline documentation so they still appear in grep.
The documentation is updated with examples, and moved to a more
appropriate location as a sub-section of the element sytle guide.
To test this out, use the associative-array in generate_hooks, where
we can now find the element's directory without searching.

This is a re-factor of element_dependencies to achieve two things --
centralising override policy and storing path names.
Firstly we want to make the override policy for elements completely
explicit. Currently, elements that wish to copy parts of other
elements walk ELEMENTS_PATH themselves and look for elements in
IMAGE_ELEMENT. How they handle duplicate elements can differ, leading
to inconsistent behaviour.
We introduce logic in element-info to find elements in each of the
directories in ELEMENT_PATHS in *reverse* order -- that is to say,
earlier entries in the paths will overwrite later ones.
For example
ELEMENT_PATHS=foo:bar:baz
will mean that "foo/element" will override "baz/element", since "foo"
is first. This should be sane to anyone familiar with $PATH.
Documentation is clarified around this point and a test-case is added.
The second thing is that we want to keep the complete path of the
elements we have chosen. We want the aforementioned elements that
walk the element list to use these canonical paths to pickup files;
this way they don't need to make local decisions about element
overrides, but can simply iterate a list and copy/merge files if they
exist.
A follow-on change (I7092e1845942f249175933d67ab121188f3511fd) will
expose this data in a separate variable that can be parsed by elements
(a further follow-on I0a64b45e9f2cfa28e84b2859d76b065a6c4590f0
modifies the elements to use this information). Thus this does not
change the status-quo -- elements that are walking ELEMENTS_PATH
themselves and can/will continue doing that.

Icf8a075224833fcfbbe2128e8802ff41c39f3c09 looked rather ugly, and it's
easy for us to expand the processing done in the arch list.
Change "arch" to a comma-separated list of architectures that should
match for install.
Add a "not-arch" list which will exclude the package from installation
on those architectures. (An aside -- I considered making it just he
one list with foo,!bar,moo but ! has special meaning in YAML, so it's
easier to have two lists).
