Ramakrishnan G 10d72ddb22 Add vmedia boot support for deploy-ironic element
deploy-ironic element currently retrieves token over tftp and
expects BOOT_IP_ADDRESS to be set.  This commit adds support for
retrieving token file from virtual media if node booted from
virtual media. Also corrects the issue for BOOT_IP_ADDRESS not set
for virtual media boot.

This is the ramdisk element.

Almost any user building a ramdisk will want to include this in their build, as it triggers many of the vital functionality from the basic diskimage-builder libraries (such as init script aggregation, busybox population, etc).

An example of when one might want to use this toolchain to build a ramdisk would be the initial deployment of baremetal nodes in a TripleO setup. Various tools and scripts need to be injected into a ramdisk that will fetch and apply a machine image to local disks. That tooling/scripting customisation can be easily applied in a repeatable and automatable way, using this element.

NOTE: ramdisks require 1GB minimum memory on the machines they are booting.

See the top-level README.md of the project, for more information about the mechanisms available to a ramdisk element.
