pkt_gen: STC - RFC 2889 Address Learning and Caching Support

This patch adds RFC-2889 address-learning-rate test and
address-caching-capacity tests. The patch includes following changes

1. 01_testcases.conf: testcase definitions are added for new tests
2. results_constants.py: 3 new results constants are added, removed
   unsupported constants
3. testcenter-rfc2889-rest.py: Added support to these two new
   tests. Removed un-necessary synchronization of db-file. 5 new
   configuration parameters are added - which are explained in (4).
4. trafficgen.rst: Configuration description for rfc2889 tests are
   added. Stale information is removed.
5. testcenter.py: Support for two new tests are added. Separate
   functions for results analysis and parameter settings are added.
6. traffic_controller_rfc2889.py: Calls to functions in testcenter.py,
   based on the traffic_type, are added.

Removed trailing whitespaces from trafficgen.rst

+   The testcenter-rfc2889-rest.py script implements the rfc2889 tests.

+   added to support these tests.
+

+The first 2 values are for address-learning test where as other 3 values are
+for the Address caching capacity test. LR: Learning Rate. AC: Address Caching.
+Maximum value for address is 16777216. Whereas, maximum for LR is 4294967295.

+Results for RFC2889 Tests: Forwarding tests outputs following values:
+
+.. code-block:: console

+    TX_RATE_PERCENT: "Transmission Rate in Percentage"
+    FRAME_LOSS_PERCENT: "Frame loss in Percentage"
+    FORWARDING_RATE_FPS: " Maximum Forwarding Rate in FPS"
+
+
+Whereas, the address caching test outputs following values,
+
+.. code-block:: console
+
+    CACHING_CAPACITY_ADDRS = 'Number of address it can cache'
+    ADDR_LEARNED_PERCENT = 'Percentage of address successfully learned'
+
+and address learning test outputs just a single value:
