Public bug reported:

The /servers API controller does a minimum nova-compute service version
check in the deployment before allowing you to create a server with
block device or virtual interface tags (the 2.32 microversion):

https://github.com/openstack/nova/blob/78c69f61ab186c3d3eb0fe5cc5114cc71f0fbdad/nova/api/openstack/compute/servers.py#L496-L499

That won't work if we have multiple cells since the services records are
in the cells databases.

So we'd really need to iterate the cells, get the minimums for each, and
then get the final minimum across all of the cells.
