Provision to configure 'tuned-nfv' profile on the DPDK compute host

Registered by Saravanan KR

In order to claim better performance of DPDK on compute nodes, it is required to setup host parameters - CPU Affinity and IRQ Pinning [1]. These parameters are managed by 'tuned' [2] when 'tuned-nfv-profile' is activated. We need to provide a mechanism to:
(1) install the tuned and tuned-nfv-profile packages
(2) activate the tuned with tuned-nfv-profile
