The await function is essentially a non-standard check_output call.
Let's use standard calls to increase maintainability.

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.

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.

If DIB_PYTHON_VERSION is < 3 on the !redhat path, that means we're on

install.

Recent changes in project-config have shown that we leave the system
in an inconsistent state when installing from source. On fedora, we
will have installed the python2 packages, but then used $DIB_PYTHON to
install python3 pip from source!
This tries to clarify the situation. As described in the document,
with package installs, we just install the $DIB_PYTHON packaged
versions.
Source installs want to take over the global namespace. This is the
price you pay for running the latest versions outside package managers
:) The only sane thing seems to be for us to normalise python2 &
python3 versions of pip, setuptools and virtualenv and then hacking
things such that "/usr/bin/pip" and "/usr/bin/virtalenv" remain
defaulted to python2 versions.
Documentation is added

Currently we install pip/virtualenv with "/usr/local/bin/dib-python".
This means that every time you create a virtualenv, the python
interpreter inside it is called "dib-python" which is confusing.
Add an env var DIB_PYTHON that points directly the to interpreter
available during build, for use when running scripts.

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.

Apt gets confused if it talks to a mirror with an older index than the
index currently cached by apt. This can happen when image builds use a
newer index than the booted image. Avoid these problems entirely by
removing those index caches at the end of image building.

The current output for package-installs-v2 is inscrutable [1]
The problem starts with process_output() which is not capturing
stderr. This means that any stderr output is dislocated from any
stdout output around it. This is *really* confusing as you get a
bunch of seemingly meaningless stderr output from any calls before you
see any stdout (e.g. in [1] you can see random yum error output that
should have been with the yum call)). The simplest thing to do is to
redirect stderr to stdout which keeps everything in sync.
This causes a slight problem, however, because pkg-map outputs both
status information and errors on stderr. To work around this but
maintain compatibility, we add a "--prefix" argument that prepends
mapped packages from pkg-map with a value we can match on. The
existing status/debug output from pkg-map is low-value; modify the
call so that it will be traced only at higher debug levels (e.g. -x
-x).
The current loop is also calling pkg-map for every package in every
element (this is why in [1] the same message is repeated over and
over). This is unnecessary; it only needs to pkg-map once for each
element, giving the package list as the arguments. Create package
lists by element and pass those to pkg-map.
As a cleanup, there is no point in printing e.output if the
process_output fails for the install because we are already tracing
it; i.e. the output, even for failures, is already in the logs.
Printing it again just duplicates the output.
[2] is an extract showing what I feel is a much more understandable
log output for a fairly complex install.

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

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.

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.
