prox: pass prox_config_dict between Processes using queue
we generate the prox_config_dict in the _run Process, but we also need it in the _traffic_runner Process to get core info. use a queue to pass the config list between the processes enable collect_kpi Change-Id: Ibaf41d606e559a87addf43d6ddaed206dbd2d20c Signed-off-by: Ross Brattain <ross.b.brattain@intel.com> Signed-off-by: Edward MacGillivray <edward.s.macgillivray@intel.com>
