virt, DPDK cluster config: Reduce HugePages alloc

Currently, the example configures the DPDK-enabled
nodes to have 32 1Gi huge pages in NUMA 0.

Define a minimum number of HugePages, so a single
instance of the DPDK checkup could run.

A single instance of the DPDK checkup requires
eight 1Gi huge pages.
