Subject: [PATCH] Add override for huge_pages configrations in nova

Some nova settings for huge_page reservation can be needed when
deploying things like ovs-dpdk to avoid running out of memory.

This change adds in the values override for setting huge_page
reservations as an example to use when overriding nova values.
