Ben Nemec e49d347ba9 Generalize logic for skipping final image generation

Since the ironic-agent element builds the ramdisk and extracts the
kernel itself, there's no need to actually generate an image at the
end of the process.  Previously the unnecessary image was being
deleted, but this wastes a bunch of time compressing and converting
the image.  It's better to just not create the image at all.

This change adds a noop element called no-final-image that
disk-image-create looks for in the element list and, if found, will
cause it to skip the final image generation.  This is more flexible
than the previous ironic-agent-specific method that would have
required changes to disk-image-create for every element that wanted
to behave similarly.

Note that this cannot be done using an environment variable, because
element environments.d entries do not propagate out to
disk-image-create.  It also doesn't make sense as a user option
because it should be set by the element author, not the user.

ironic-agent

Builds a ramdisk with ironic-python-agent. More information can be found at:: https://git.openstack.org/cgit/openstack/ironic-python-agent/

Beyond installing the ironic-python-agent, this element does the following:

Installs the dhcp-all-interfaces so the node, upon booting, attempts to obtain an IP address on all available network interfaces.
Disables the iptables service on SysV and systemd based systems.
Disables the ufw service on Upstart based systems.
Installs packages required for the operation of the ironic-python-agent::

qemu-utils parted hdparm util-linux genisoimage
When installing from source, python-dev and gcc are also installed in order to support source based installation of ironic-python-agent and its dependencies.
Install the certificate if any, which is set to the environment variable DIB_IPA_CERT for validating the authenticity by ironic-python-agent. The certificate can be self-signed certificate or CA certificate.

This element outputs three files:

$IMAGE-NAME.initramfs: The deploy ramdisk file containing the ironic-python-agent (IPA) service.
$IMAGE-NAME.kernel: The kernel binary file.
$IMAGE-NAME.vmlinuz: A hard link pointing to the $IMAGE-NAME.kernel file; this is just a backward compatibility layer, please do not rely on this file.

Note

The package based install currently only enables the service when using the systemd init system. This can easily be changed if there is an agent package which includes upstart or sysv packaging.

Note

Using the ramdisk will require at least 1.5GB of ram
