[RFE] Provide a convenience way to bulk-update IPA images on many nodes

[sergiiF]

While supporting the cluster with an Ironic deployment we met an issue with the case when we need to update IPA image.

The problem is that there is no way to update ‘deploy_kernel’ and ‘deploy_ramdisk’ parameters on already provisioned hosts. It’s also not really convenient to update hundreds or even thousands of hosts just because you need to do a minor change in IPA image.
It will be really nice to have an ability to specify image name instead of image uuid in ‘deploy_xxx’ parameters.

Even better solution could be a standalone DB record that defines the provision driver details, like API agent, and a reference from node to such a record.

Hi! I think this RFE would require a spec.
