Michal Berger c1e9ed6d4c perf/vhost: Auto generate VM cpu and disk map configs
The configuration is generated based on existing host's NUMA
topology (as seen via sysfs) instead of a total number of cpus as
it was done before. New logic attempts to load balance VMs and
their cpus based on nvme drives' NUMA location. If there is no
enough cpus left under the target node, all remaining nodes are
checked. For the sake of the performance, cpus are not mixed
between different numa nodes.

Disk map is created by mapping VMs to existing nvme drives
based on their NUMA location. Extra VMs are assigned in bus
order of the nvme drives.

SPDK cpus are split by matching the VM-to-nvme NUMA ratio.
Static list can be defined as well to override this behavior.
