CSIT-235: Switched Port Analyzer mirroring (SPAN) - IPv4

 - add library for SPAN setup
 - add telemetry traffic script and a keyword to run it
 - add "telemetry" folders for python and robot libraries
 - move IPFIX libraries to these new folders
 - add first SPAN test case, mirroring IPv4 ICMP packets
