0368052a2f Take --params from environment
DIB_BLOCK_DEVICE_PARAMS_YAML should be exported, and the
dib-block-device will take this as the value of --params.  Remove this
to simplify the command-line

e21935626b Refactor block-device base functions.
As part of the final steps, refactor the bits belonging
to block device and functions. This is a partial refactor
from I3600c6a3d663c697b59d91bd3fbb5e408af345e4

91ba21dd6c Set LC_ALL in disk-image-create
It seems that the redhat nodepool job is quite reliably geting a
"floating point" error during centos image build.  This happens after
03-yum-cleanup which is pruning the locales.  This might be a
red-herring, since the logs are full of

  /bin/bash: warning: setlocale: LC_ALL: cannot change locale (C.UTF-8)

I think in our recent de-puppetisation of hosts, something might have
changed that is setting LC_ALL=C.UTF-8 for the jenkins user, at least
on Ubuntu.  This is a problem for centos, as it doesn't have C.UTF-8
locale.  I then think using the invalid locale is what leads the the
floating-point error when doing some maths in dib-run-parts to
calculate runtimes.

We are currently overriding LANG, but we really want LC_ALL to ensure
this applies globally.

943f1ccf04 Refactor block_device: isolate the getval call
Add a new getval call that allows to retrieve values
from the block device. Also isolating the block device
information into a 'blockdev' dictionary entry, to better
return it with the getval command.

This is a refactor from the original code at
I3600c6a3d663c697b59d91bd3fbb5e408af345e4.

803d40b0c6 Refactor block_device: passing command line parameters
The original approach was to pass each and every command
line parameter to the block device.  While the block device
functionality gets extended, this is not any longer practical.

Instead of passing in all the parameters separately this patch
collects these in a YAML file that is passed in to the block device
layer.

95503b4201 Move do_extra_package_install to run in install phase
This change move "do_extra_package_install" from pre-install to install
phase.

Extra packages are added by user request using the flag "-p", This
package should not be something the elements depend on.
The reason behind this patch is to move the extra package install to
a proper phase, Also more reasonable if base element run package update
to be before we install extra packages.

f06231ee08 Use DIB_PYTHON_EXEC to run commands
DIB_PYTHON_EXEC was added in I5fab0e192c3a2dad8f60e821c184479e24e33bcd
to export the python that disk-image-create is running under.  If dib
is installed with python3 then just calls "python" (python2) to run
sub-scripts, it fails to find itself.

This has been tested in devstack gates that use py3x

aa90f7991a Ignore missing path in unmount_dir
If the path is missing, unmount_dir currently exits with an error which
unintentionally aborts cleanup efforts early. This change makes
unmount_dir idempotent by exiting successfully if a directory doesn't
exist.

6802cf7100 Run dib-run-parts out of /tmp
The dib-run-parts element was copying our internal version of
dib-run-parts into /usr/local/bin to be used running scripts inside
the target chroot.  However, it never cleaned up after itself.  This
means all images were left with an unmanaged local install of
dib-run-parts.

This copies dib-run-parts into the hooks directory of the chroot and
runs it from there.  It is cleaned up automatically on the exit path.

The dib-run-parts element is no longer required and it has been
removed from all dependencies.  It is left with a deprecation notice
in the README.  For compatability we convert it to simply install
dib-utils.

Codesearch shows no users depending on this unintentional implicit
install.  Note os-refresh-config depends on dib-utils and thus will
have an explicitly installed version.

fd424757a6 Don't provide dib-run-parts
It was an oversight during v2 development for dib to start providing
dib-run-parts.  The intention was for dib to use a vendored
dib-run-parts directly from $_LIB and have no dependencies on
dib-utils at all.  By exporting dib-run-parts, we created an
unintentional conflict with the dib-utils package which provides the
same script.

Tools that depend on dib-utils are unaffected by this
(os-refresh-config).

The only tool that installs diskimage-builder and then assumes
dib-run-parts is available in the path is instack.  I have proposed
Ibfe972208df40fa092b11b5419043524c903f1b4 to modify that to use our
internal version.

866a06f92d Refactor: block-device partitioning cleanup
Now that the main partitioning refactor patch is merged, there is
a small relict of handling partitions still in the disk-image-create
main.

This patch moves the functionality from disk-image-create to the
block-device/partitioning module: it is mostly a rewrite of the
original bash code in python.

ec7f56c1b2 Refactor: block-device handling (partitioning)
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.

d65678678e Move dib-run-parts into diskimage-builder
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.

7446c32197 Move diskimage-image-create to an entry point
It has always been a weird thing that dib is a python package, but
is totally driven by the disk-image-create script.  It creates this
strange division that is hard to explain.

This moves disk-image-create to a regular python entry-point

Currently, this simply exec()s the original disk-image-create script.

However, we now have a (private) interface between disk-image-create
written in python and the driver shell script.  Here's some things we
could do, for example:

* Argument parsing is generally nicer in Python, and then end result
  is mostly just setting environment variables to flag different things
  in the shell script.  I could see us moving the argument-parsing into
  diskimage_builder.disk_image_create:main() and just setting things in
  os.environ before the exec()).

* I7092e1845942f249175933d67ab121188f3511fd sets IMAGE_ELEMENT_YAML in
  disk-image-create by calling-back to element-info.  We can just call
  element_dependencies.find_all_elements() in here an export is to
  os.environ before disk-image-create starts.

* remove need for ramdisk-image-create symlink by just exporting
  IS_RAMDISK based on sys.argv[1] value

* you could even unit test some of this :)

97c01e48ed Move elements & lib relative to diskimage_builder package
Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).

The problem with this is that editable/development installs (pip -e)
do *not* install data_files.  Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.

data_files is really the wrong thing to use for what are essentially
assets of the program.  data_files install works well for things like
config-files, init.d files or dropping documentation files.

By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from.  In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].

We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.

Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.

I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.

Unfortunately, this has to move to work with setuptools.  You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.

[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do.  Essentially for us it's returning
__file__.
