bug_fix: process pkt_size/duration from cli

Refactor rfc25444_duration to duration and update the --test-params help
to show the type of parameters that can be set from the cli. Also
configure pkt_sizes so that it can be modified from the CLI. Also fixes
the tcl script to configure framesize properly (to the value selected
and not the default 64b).
