[dpdk] nailgun should validate that huge and kvm are enabled when dpdk requested

[Atsuko Ito]

1. Create VLAN cluster
2. Mark interface enp0s5 as DPDK and put Private net on it
3. Make NO changes in Node attributes for this node
4. Leave QEMU as Hypervisor type
5. Deploy cluster

Expected result: nailgun should not allow this configuration, because hugepages and kvm is required to use feature.
Actual result: deploy fails on l23network, because openvswitch-dpdk is failed to start due to absence of hugepages.
