Workflow input parameter update in plan-environment

Browse Source 
derive_parameters workflow input parameter needs to be
changed as num_phy_cores_per_numa_node_for_pmd
instead of number_of_pmd_cpu_threads_per_numa_node.
The performance varies based on the physical core
rather than the logical CPUs. Which means, user should
be able to decide the number of physical cores,
which is proportional to data rate.
Implements: blueprint tripleo-derive-parameters
