Support ironic rescue mode in under and overcloud

Registered by Dmitry Tantsur on 2018-03-14

Starting with the Queens release, ironic supports rescue operation - booting a ramdisk to recover a malfunctioning instance. Some minimum work will be required to support it in TripleO, mostly making sure our ramdisk supports the feature.
