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.
