ixia: Add support of LISTs in TRAFFIC

The control script for Ixia (i.e. Ixia and IxNet classes)
is written in TCL and thus VSPERF must translate TRAFFIC
dictionary into TCL notation. The method for data type
conversion was updated to correctly process new 'capture'
settings, which uses python lists for tx and rx capture
ports definition.

JIRA: VSPERF-556
