James Parker db22bdcab5 Add multi-numa tests for masked policy ...

Add aditional tests based around [1] that introduces guest deployments
with multi-NUMA. The first new test is based on a symmetrical load with
the same number of vCPUs and memory per physical NUMA. The second test
limits a quarter of the resources to land on one NUMA and the remaining
75% on the other.

For example a 4 vCPU 1024 RAM guest would configured NUMA 0 to hold 1
vCPU and 256 with NUMA 1 would hold the remaining for the guest. This
type of deployment models high scale NFV architecture, where the control
plane vCPUs may all be shared on a specific NUMA while the dataplane
vCPUs would want to be dedicated and land on a NUMA that is connected to
the compute host's NICs.
