Add base tests for NUMA CPU pinning
Add base tests with preparing env for NUMA nodes NUMA nodes will be configuring using fuel-devops for every node in cluster with equal value. If there are no NUMAs on compute node, test will fail. Change-Id: I8d1c7475e848b8df5a7cc05d310dd584a501752d Implements: blueprint test-numa-cpu-pinning
