Subject: Providing parameters specific to a workflow via plan-environment

Parameters which are not part of the heat environment template
are required by the worflows like derive parameters. In order to
seprate from the heat environment parameters, the workflow only
parameters will be provided via plan-environement section,
workflow_parameters.
Implements: blueprint tripleo-derive-parameters

+=================================
+Samples for plan-environment.yaml
+=================================
+
+The ``plan-environment.yaml`` file provides the details of the plan to be
+deployed by TripleO. Along with the details of the heat environments and
+parameters, it is also possible to provide workflow specific parameters to the
+TripleO mistral workflows. A new section ``workflow_parameters`` has been
+added to provide workflow specific parameters. This provides a clear
+separation of heat environment parameters and the workflow only parameters.
+These customized plan environment files can be provided as with ``-p`` option
+to the ``openstack overcloud deploy`` and ``openstack overcloud plan create``
+commands. The sample format to provide the workflow specific parameters::
+
+  workflow_parameters:
+    tripleo.derive_params.v1.derive_parameters:
+      # DPDK Parameters
+      number_of_pmd_cpu_threads_per_numa_node: 2
+
+
+All the parameters specified under the workflow name will be passed as
+``user_input`` to the workflow, while invoking from the tripleoclient.
