Add CPU pinning support for node context

JIRA: YARDSTICK-573

Since the yardstick framework now has supported an improved node type context,
this patch adds support for VM vcpu pinning ability in the node type context.
It provides several scripts that can be used to configurate the controller and
compute nodes.
