This change removes the following parameters, which were used by
undercloud Nova.
- KeyName
- Overcloud{{role.name}}Flavor
- {{role.name}}SchedulerHints
- {{role.name}}Image
This also removes the NodeUserData resource because it depends on
cloud-init and nova metadata and is no longer used since Nova was
removed from baremetal node provisioning.
Finally, this change makes deployed server method used by default, and
removes remaining implementation to keep the resource compatible with
OS::Nova::Server.
