In 21.0.0 Ussuri we were completed the nova-cyborg interaction feature,
but there are some issue when multiple create instances.
Creating servers with accelerators provisioned with the Cyborg service,
if a flavor asks for resources that are provided by nested Resource
Provider inventories (eg. VGPU) and the user wants multi-create (ie. say
--max 2) then the scheduler could be returning a NoValidHosts exception
even if each nested Resource Provider can support at least one specific
instance, if the total wanted capacity is not supported by only one
nested RP.
For example,creating servers with accelerators provisioned with the
Cyborg service, if two children RP have 4 VGPU inventories each:
- you can ask for a flavor with 2 VGPU with --max 2
- but you can't ask for a flavor with 4 VGPU and --max 2

List bullets in the top level have to be left justified,
otherwise we get "<blockquote>" html tags inserted.
