cli: Modify configuration via CLI
In the past, only a few configuration parameters could be modified via --test-params CLI argument and it was not easy to find out their complete list. This patch adds support for generic modification of any configuration parameter via CLI argument --test-params or by "Parameters" section of testcase definition. Thus it is possible to customize a vsperf configuration environment per testcase or for each vsperf execution. Old CLI parameters duration, pkt_sizes, rfc2544_tests and rfc2889_trials were renamed to TRAFFICGEN_DURATION, TRAFFICGEN_PKT_SIZES, TRAFFICGEN_RFC2544_TESTS and TRAFFICGEN_RFC2889_TRIALS to be consistent with other configuration parameters.

-1. Command line arguments
-2. Environment variables

+2. Command line arguments
+3. Environment variables
+4. Configuration file(s)

+Overriding values defined in configuration files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The configuration items can be overridden by command line argument
+``--test-params``. In this case, the configuration items and
+their values should be passed in form of ``item=value`` and separated
+by semicolon.
+
+Example:
+
+.. code:: console
+
+ $ ./vsperf --test-params "TRAFFICGEN_DURATION=10;TRAFFICGEN_PKT_SIZES=(128,);" \
+ "GUEST_LOOPBACK=['testpmd','l2fwd']" pvvp_tput
+
+The second option is to override configuration items by ``Parameters`` section
+of the test case definition. The configuration items can be added into ``Parameters``
+dictionary with their new values. These values will override values defined in
+configuration files or specified by ``--test-params`` command line argument.
+
+Example:
+
+.. code:: python
+
+ "Parameters" : {'TRAFFICGEN_PKT_SIZES' : (128,),
+ 'TRAFFICGEN_DURATION' : 10,
+ 'GUEST_LOOPBACK' : ['testpmd','l2fwd'],
+ }
+
+**NOTE:** In both cases, configuration item names and their values must be specified
+in the same form as they are defined inside configuration files. Parameter names
+must be specified in uppercase and data types of original and new value must match.
+Python syntax rules related to data types and structures must be followed.
+For example, parameter ``TRAFFICGEN_PKT_SIZES`` above is defined as a tuple
+with a single value ``128``. In this case trailing comma is mandatory, otherwise
+value can be wrongly interpreted as a number instead of a tuple and vsperf
+execution would fail. Please check configuration files for default values and their
+types and use them as a basis for any customized values. In case of any doubt, please
+check official python documentation related to data structures like tuples, lists
+and dictionaries.
+
+**NOTE:** Vsperf execution will terminate with runtime error in case, that unknown
+parameter name is passed via ``--test-params`` CLI argument or defined in ``Parameters``
+section of test case definition. It is also forbidden to redefine a value of
+``TEST_PARAMS`` configuration item via CLI or ``Parameters`` section.
