Now that deploy has been renamed to deploy-baremetal, README.md needs

Adds a new pkg-map element which can be used to install
packages based on an in element 'pkg-map' JSON config
file format.
As part of this change we expose DIB's IMAGE_ELEMENT variable
so that we can have access to the element names which are being
installed in a clean manner.
This change is intended to decouple elements from DIB
and allow new elements to support multiple distributions
(with various package naming schemes) without having to
constantly maintain DIB's various bin/map-packages files.

This change defines indentation rules for the elements. It enforces
the use of 4 spaces which is already the devstack standard.

An element can define a list of elements provided by itself. This allows
using an alternative element and keeping element dependencies at the
same time. This will be needed for example for mariadb element which will be
an alternative to mysql element - mysql dependency can be kept everywhere
but user can choose mariadb explicitly as a replacement by putting "mysql"
into "element-provides" file.

Move whether the package or source install type is enabled out of the
source-repositories element and into the base element.
source-repositories wasn't a great fit for this functionality to begin
with.
Specify the install type for an element via the
DIB_INSTALLTYPE_<install_dir_prefix> environment variable.
Additionally with this approach, any new install type can be added
in an element, without having to update source-repositories or anything
in dib.
You could just write your install type implementation under
nova-foo-install, then define DIB_INSTALLTYPE_nova=foo in your
environment, and the scripts under nova-foo-install would get run during
the image build.
Source installs (any scripts under <install_dir_prefix>-source-install)
is the default install type for all elements.

This orders the phase subdirectories by execution order, adds

Rather than using a script to mount the image using nbd to extract the
kernel and ramdisk, make a new element called baremetal, which contains
a cleanup.d script that will copy them out to <image name>.{vmlinuz,initrd}.

Using a custom pypi mirror can be very convenient, making image builds
substantially faster - because we create multiple virtual
environments we benefit more than single-virtualenv users would.

Manually listing the mount points that need cleanup is not
maintainable and makes it hard to write elements that use bind
mounting to inject resources into the build environment.

Most of our build process runs as root and the overhead of explicitly
tracking sudo commands in the shipped sudoers.d file, plus the
operational overhead of keeping the sudoers.d file updated on build
hosts over time, is now considered to be unnecessary.
Instead, we now document that the build process will expect sudo
commands to work and the operator must make this happen (either by
running as root, via sudo -E, or allowing passwordless sudo for the
build user).

Add a potent example (and simply remedy) of how element authors can
unwittingly conflict with each other in ways that it is almost
impossible for us to guard against with low level policy/mechanism in
di-b. Fixes bug 1181309.

A user running di-b several times while developing an element may not
want to drop to a shell in all cases but may only want to do so if one
of their in target hooks failed.
This patch gives them the ability to do so, If break=after-error is set
then a user will be provided a in target shell taking over from where the
last failed command left off.

Complex image builds can download hundreds of MB of data from the
internet with many separate lookups. It would be nice to allow users
to ask for a fast build where those lookups are entirely avoided,
using locally cached resources (where possible). This new interface
allows users to signal to elements that they wish to operate without
updating cached resources, which will in turn allow us to avoid
checking for stale data at all.
As part of this I've also documented where we cache data, so that
things like the ccache cache dir and image cache files are not a
surprise to users.

Ramdisks are now built inside a chroot which is built by the normal

Apply kernel command line parameters to force Linux to remain in text

and this is incompatible with common Lights Out Management hardware
which is able to intercept text mode consoles to display them remotely.

For machines with low RAM (or no access to /proc/meminfo) the builder
will still run, but will just build inside the filesystem that is
hosting /tmp. This will result in a slower build (especially if there
are a lot of .deb packages installed).

Qemu-nbd does not perform well with older versions of qemu due to
the lack of writeback caching mode. It also only builds qcow2 images
and there is a desire for raw image support. Finally, qemu-nbd makes
it very difficult to build images concurrently due to the somewhat
opaque nature of how it selects a /dev/nbd# device. losetup, on
the other hand, makes this process very straight forward.

Post install scripts are useful because they can perform tasks you want
to handle after the OS/application install but before the first boot
of the image. e.g: Clean the cache left by the package manager reducing
the size of the image.
