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

+| | ... | [Cfg] On DUT1 configure IPv4 address, add ARP entry for one TG \
+| | ... | interface and set SPAN mirroring from one DUT interface to the other.
+| | ... | [Ver] Make TG send an ICMP packet to DUT through one interface,\
+| | ... | then receive a copy of sent packet and of DUT's ICMP reply\
+| | ... | on the other interface.
