This patch is fixing a syntax error in the 70-ironic-root-device init
script for the deploy-ironic element.

Closes-Bug: #1531835
This patch is extending the root device hints to also look at
ID_WWN_WITH_EXTENSION and ID_WWN_VENDOR_EXTENSION from udev.
Prior to this patch the bash ramdisk only cared about ID_WWN but in some
systems in some platforms with a RAID controller, this ID can be same
even if they are different disks (see bug 1516641).

As part of the blueprint root-device-hints Ironic will pass some to the
deploy ramdisk some hints about which disk device it should pick to be
root device (the one where the image will be deployed on).
Before the deploy ramdisk would pick the first device it finds, but as the
machine could have more than one SATA, SCSI or IDE disk controllers the
order in which their corresponding device nodes are added is arbitrary
causing devices like /dev/sda and /dev/sdb switching around on each
boot time.
Plus, as people are adding support to build RAID arrays in Ironic we need
a way to tell it to use the just created device to be the root device.
The list of hints that could be passed to the deploy ramdisk so it finds
the right disk is:
* wwn (STRING): unique storage identifier
* serial (STRING): disk serial number
* model (STRING): device identifier
* vendor (STRING): device vendor
* size (INT): The size of the disk in GB
If not hints are passed, the deploy ramdisk will continue to do what it
did before to find the disk.
