pkt_gen: Spirent Testcenter RFC 2889 Support

The changes/additions, apart from spirent testcenter-specific, also
includes
to some files in conf (01_testcase and 03_traffic) and core (result-
constants, traffic_controller and component_factory) folders.

Currently, only RFC2889 Forwarding testcase is supported.

Incorporated following review suggestions:
1. Log level fixes
2. Removing unused function in results_constants.py
3. Added documentation to docs/configguide/trafficgen.rst. Userguide
   will be updated once other RFC2889 tests are implemented.
4. string matching in component_factory.
5. Remove Trailing Whitespaces

JIRA: VSPERF-286
