Nested allocations are only partially supported in nova-manage placement
heal_allocations CLI. This patch documents the missing support and
blocks healing instances with VGPU or Cyborg device profile request in
the embedded flavor. Blocking is needed as if --forced is used with such
instances then the tool could recreate an allocation ignoring some of
these resources.
