Due to an Ansible bug, kayobe fails to provision a seed VM using Ansible
2.6. Accessing hostvars via an intermediate variable causes Ansible not
to template the variable.
Work around the issue until it's fixed upstream in Ansible.

Story: 2004759
Task: 28868
The libvirt_vm_vcpus and libvirt_vm_memory_mb variables are required by
the stackhpc.libvirt-vm role even when setting libvirt_vm_state to
absent. Without these variables, `kayobe seed vm deprovision` fails with
the following error:
FAILED! => {"msg": "'libvirt_vm_vcpus' is undefined"}
