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 Change-Id: I0195720ab2f8cf2c3a5aa490d66166bdca0afcb0 Signed-off-by: Sridhar K. N. Rao <sridhar.rao@spirent.com>
