It chooses one of the two options in the order as below:
1. Image deployed has a meta-property 'boot_iso' in Glance. This should
refer to the UUID of the boot_iso which exists in Glance.
2. Generates a boot ISO on the fly using kernel and ramdisk mentioned in
the image deployed. It uploads the generated boot ISO to Swift.
:param task: a TaskManager instance containing the node to act on.
:param root_uuid: the uuid of the root partition.
:returns: the information about the boot ISO. Returns the information in
the format 'glance:<glance-boot-iso-uuid>' or
'swift:<swift-boot_iso-object-name>'. In case of Swift, it is assumed
that the object exists in CONF.ilo.swift_ilo_container.
On error finding the boot iso, it returns None.
:raises: MissingParameterValue, if any of the required parameters are
missing in the node's driver_info or instance_info.
:raises: InvalidParameterValue, if any of the parameters have invalid
value in the node's driver_info or instance_info.
:raises: SwiftOperationError, if operation with Swift fails.
:raises: ImageCreationFailed, if creation of boot ISO failed.
