After this commit, users may start a dpdk-enabled ovs setup as a non-root user. This is accomplished by exporting the $HOME directory, which dpdk uses to fill in it's semi-persistent RTE configuration. This change may be a bit controversial since it modifies /dev/hugepages as part of starting the ovs-vswitchd to set a hugetlbfs group ownership. This is used to enable writing to /dev/hugepages so that the dpdk_init will successfully complete. There is an alternate way of accomplishing this - namely to initialize DPDK before dropping privileges. However, this would mean that if DPDK ever grows an uninit / reinit function, non-root ovs likely could never use it. This does not change OvS+DPDK's SELinux requirements. It still must be disabled.
