teststeps: Generic support of step driven tests

In the past, step driven testcases were supported
only by integration testcases. This patch adds generic
support of TestSteps for both integration and performance
testcases. Step driven test were improved to support
modification of existing deployment. As part of
the patch a refactoring of traffic controllers
were performed. Traffic controllers were modified
to support trafficgen-off and trafficgen-pause
modes in all possible ways of trafficgen invocation.

 The standard tests included are defined inside the
 ``conf/integration/01_testcases.conf`` file.
 
-Test Steps
-----------
-
-Execution of integration tests are done on a step by step work flow starting
-with step 0 as defined inside the test case. Each step of the test increments
-the step number by one which is indicated in the log.
-
-.. code-block:: console
-
-    (testcases.integration) - Step 1 - 'vswitch add_switch ['int_br1']' ... OK
-
-Each step in the test case is validated. If a step does not pass validation the
-test will fail and terminate. The test will continue until a failure is detected
-or all steps pass. A csv report file is generated after a test completes with an
-OK or FAIL result.
-
-Test objects and their functions
---------------------------------
-
-Every test step can call a function of one of the supported test objects. The list
-of supported objects and their most common functions follows:
-
-    * ``vswitch`` - provides functions for vSwitch configuration
-
-      List of supported functions:
-
-        * ``add_switch br_name`` - creates a new switch (bridge) with given ``br_name``
-        * ``del_switch br_name`` - deletes switch (bridge) with given ``br_name``
-        * ``add_phy_port br_name`` - adds a physical port into bridge specified by ``br_name``
-        * ``add_vport br_name`` - adds a virtual port into bridge specified by ``br_name``
-        * ``del_port br_name port_name`` - removes physical or virtual port specified by
-          ``port_name`` from bridge ``br_name``
-        * ``add_flow br_name flow`` - adds flow specified by ``flow`` dictionary into
-          the bridge ``br_name``; Content of flow dictionary will be passed to the vSwitch.
-          In case of Open vSwitch it will be passed to the ``ovs-ofctl add-flow`` command.
-          Please see Open vSwitch documentation for the list of supported flow parameters.
-        * ``del_flow br_name [flow]`` - deletes flow specified by ``flow`` dictionary from
-          bridge ``br_name``; In case that optional parameter ``flow`` is not specified
-          or set to an empty dictionary ``{}``, then all flows from bridge ``br_name``
-          will be deleted.
-        * ``dump_flows br_name`` - dumps all flows from bridge specified by ``br_name``
-        * ``enable_stp br_name`` - enables Spanning Tree Protocol for bridge ``br_name``
-        * ``disable_stp br_name`` - disables Spanning Tree Protocol for bridge ``br_name``
-        * ``enable_rstp br_name`` - enables Rapid Spanning Tree Protocol for bridge ``br_name``

-Test Macros
------------
-
-Test profiles can include macros as part of the test step. Each step in the
-profile may return a value such as a port name. Recall macros use #STEP to
-indicate the recalled value inside the return structure. If the method the
-test step calls returns a value it can be later recalled, for example:
-
-.. code-block:: python
-
-    {
-        "Name": "vswitch_add_del_vport",
-        "Deployment": "clean",
-        "Description": "vSwitch - add and delete virtual port",
-        "TestSteps": [
-                ['vswitch', 'add_switch', 'int_br0'],               # STEP 0
-                ['vswitch', 'add_vport', 'int_br0'],                # STEP 1
-                ['vswitch', 'del_port', 'int_br0', '#STEP[1][0]'],  # STEP 2
-                ['vswitch', 'del_switch', 'int_br0'],               # STEP 3
-             ]
-    }
-
-This test profile uses the vswitch add_vport method which returns a string
-value of the port added. This is later called by the del_port method using the
-name from step 1.
-
-It is also possible to use negative indexes in step macros. In that case
-``#STEP[-1]`` will refer to the result from previous step, ``#STEP[-2]``
-will refer to result of step called before previous step, etc. It means,
-that you could change ``STEP 2`` from previous example to achieve the same
-functionality:
-
-.. code-block:: python
-
-                ['vswitch', 'del_port', 'int_br0', '#STEP[-1][0]'],  # STEP 2
-
-Also commonly used steps can be created as a separate profile.
-
-.. code-block:: python
-
-    STEP_VSWITCH_PVP_INIT = [
-        ['vswitch', 'add_switch', 'int_br0'],           # STEP 0
-        ['vswitch', 'add_phy_port', 'int_br0'],         # STEP 1
-        ['vswitch', 'add_phy_port', 'int_br0'],         # STEP 2
-        ['vswitch', 'add_vport', 'int_br0'],            # STEP 3
-        ['vswitch', 'add_vport', 'int_br0'],            # STEP 4
-    ]
-
-This profile can then be used inside other testcases
-
-.. code-block:: python
-
-    {
-        "Name": "vswitch_pvp",
-        "Deployment": "clean",
-        "Description": "vSwitch - configure switch and one vnf",
-        "TestSteps": STEP_VSWITCH_PVP_INIT +
-                     [
-                        ['vnf', 'start'],
-                        ['vnf', 'stop'],
-                     ] +
-                     STEP_VSWITCH_PVP_FINIT

-HelloWorld and other basic Testcases
-------------------------------------
-
-The following examples are for demonstration purposes.
-You can run them by copying and pasting into the
-conf/integration/01_testcases.conf file.
-A command-line instruction is shown at the end of each
-example.
-
-HelloWorld
-^^^^^^^^^^
-
-The first example is a HelloWorld testcase.
-It simply creates a bridge with 2 physical ports, then sets up a flow to drop
-incoming packets from the port that was instantiated at the STEP #1.
-There's no interaction with the traffic generator.
-Then the flow, the 2 ports and the bridge are deleted.
-'add_phy_port' method creates a 'dpdk' type interface that will manage the
-physical port. The string value returned is the port name that will be referred
-by 'del_port' later on.
-
-.. code-block:: python
-
-    {

-        "Description": "My first testcase",
-        "Deployment": "clean",
-        "TestSteps": [
-            ['vswitch', 'add_switch', 'int_br0'],   # STEP 0
-            ['vswitch', 'add_phy_port', 'int_br0'], # STEP 1
-            ['vswitch', 'add_phy_port', 'int_br0'], # STEP 2
-            ['vswitch', 'add_flow', 'int_br0', {'in_port': '#STEP[1][1]', \
-                'actions': ['drop'], 'idle_timeout': '0'}],
-            ['vswitch', 'del_flow', 'int_br0'],
-            ['vswitch', 'del_port', 'int_br0', '#STEP[1][0]'],
-            ['vswitch', 'del_port', 'int_br0', '#STEP[2][0]'],
-            ['vswitch', 'del_switch', 'int_br0'],
-        ]
-
-    }
-
-To run HelloWorld test:
-
-  .. code-block:: console
-
-    ./vsperf --conf-file user_settings.py --integration HelloWorld
-
-Specify a Flow by the IP address
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-The next example shows how to explicitly set up a flow by specifying a
-destination IP address.
-All packets received from the port created at STEP #1 that have a destination
-IP address = 90.90.90.90 will be forwarded to the port created at the STEP #2.
-
-.. code-block:: python
-
-    {

-        "Description": "Phy2Phy with rule on L3 Dest Addr",

-            ['vswitch', 'add_phy_port', 'int_br0'], # STEP 2

-            ['vswitch', 'del_port', 'int_br0', '#STEP[2][0]'],
-            ['vswitch', 'del_switch', 'int_br0'],

-    },
-
-To run the test:
-
-  .. code-block:: console
-
-    ./vsperf --conf-file user_settings.py --integration p2p_rule_l3da
-
-Multistream feature
-^^^^^^^^^^^^^^^^^^^
-
-The next testcase uses the multistream feature.
-The traffic generator will send packets with different UDP ports.
-That is accomplished by using "Stream Type" and "MultiStream" keywords.
-4 different flows are set to forward all incoming packets.
-

-PVP with a VM Replacement
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-This example launches a 1st VM in a PVP topology, then the VM is replaced
-by another VM.
-When VNF setup parameter in ./conf/04_vnf.conf is "QemuDpdkVhostUser"
-'add_vport' method creates a 'dpdkvhostuser' type port to connect a VM.

-VM with a Linux bridge
-^^^^^^^^^^^^^^^^^^^^^^
-
-In this example a command-line parameter allows to set up a Linux bridge into
-the guest VM.
-That's one of the available ways to specify the guest application.
-Packets matching the flow will be forwarded to the VM.
