Saravanan KR a3e4a90636 NFV: Support for config-download to deploy node with kernel args
For NFV deployments, specific kernel args should be applied and
the nodes should be restarted before running the NetworkDeployment.
It is supported in the heat deployment via PreNetworkConfig. In the
config-download mechanism, ansible steps need to be improved
to handle the reboot and wait for the node.

location to cores on socket, number of hyper-threaded logical cores, and

OvsDpdkSocketMemory is assigned. If using hyperthreading then specify
both logical cores that would equal the physical core. Also, specifying
more than one core will trigger multiple PMD threads to be spawned which
may improve dataplane performance.
