traffic: Configurable traffic details

Traffic generated by traffic generator is based on default
values and their modifications specific to particular testing
scenario. Traffic default values were defined inside VSPERF
code and it was not possible to change them. This patch introduces
new TRAFFIC dictionary inside 03_traffic.conf. Thus user can
modify any of TRAFFIC values either in configuration file
or by CLI or by 'Parameters' section of testcase definition.
Following CLI options were obsoleted by this patch:
    'bidirectional', 'traffic_type', 'iload', 'multistream',
    'stream_type' and 'pre-installed_flows'
Following CLI option was renamed to be consistent with other options:
    'tunnel_type' => 'TUNNEL_TYPE'
Following sections of testcase definition were obsoleted:
    "Traffic Type", "biDirectional", "MultiStream", "Stream Type",
    "Pre-installed Flows", "Flow Type" and "iLoad"
New TRAFFIC dictionary should be used instead of old CLI options
and old testcase definition sections. Testcase definitons,
yardstick sample testcases and documentation were updated to reflect
configuration changes.
