To avoid duplication, remove image building information from IPA docs.
Instead, add information about pre-built images.

============== ==============
Unlike most other python software, you must build an IPA ramdisk image before
use. This is because it's not installed in an operating system, but instead is
run from within a ramdisk.
diskimage-builder Unlike most other python software, you must build or download an IPA ramdisk
----------------- image before use. This is because it's not installed in an operating system,
but instead is run from within a ramdisk.
A production ready way to build a ramdisk image for IPA is by using Two kinds of images are published on every commit from every branch of IPA:
ironic-python-agent-builder_. The ``ironic-python-agent-ramdisk``
diskimage-builder element builds the IPA ramdisk, which installs all the
required packages and configures services as needed.
tinyipa * DIB_ images are suitable for production usage and can be downloaded from
------- https://tarballs.openstack.org/ironic-python-agent/dib/files/.
* TinyIPA_ images are suitable for CI and testing environments and can be
downloaded from
https://tarballs.openstack.org/ironic-python-agent/tinyipa/files/.
Now this method is provided by ironic-python-agent-builder_ If you need to build your own image, use the tools from the
repository. It provides a set of scripts to build a ironic-python-agent-builder_ project.
Tiny Core Linux-based deployment kernel and ramdisk (code name ``tinyipa``)
under ``tinyipa`` folder.
`Tiny Core Linux <http://tinycorelinux.net/>`_
is a very minimalistic Linux distribution.
Due to its small size and decreased RAM requirements
it is mostly suitable for usage in CI with virtualized hardware,
and is already used on a number of gate jobs in projects under
OpenStack Baremetal program.
On the other hand, due to its generally newer Linux kernel it also known to
work on real hardware if the kernel supports all necessary components
installed.
Please refer to ``tinyipa/README.rst`` for more information and
build instructions.
ISO Images
----------
Additionally, the IPA ramdisk can be packaged inside of an ISO for use with
supported virtual media drivers. Simply use the ``iso-image-create`` utility
packaged with IPA, pass it an initrd and kernel. e.g.::
./iso-image-create -o /path/to/output.iso -i /path/to/ipa.initrd -k /path/to/ipa.kernel
This is a generic tool that can be used to combine any initrd and kernel into
a suitable ISO for booting, and so should work against any IPA ramdisk.
