ci/broadcom: use SNMP to turn on/off devices

So far we were using a telnet-based script to communicate with the PoE
Switch to turn on/off the network ports the DUTs are connected.

But this script does not seem very reliable because from time to time the
switch fails to execute the steps in the script.

As the PoE Switch we use is a smart one with support for SNMP protocol,
it would be easier to use it to handle it, which allows to turn on/off
the ports without going through the nasty telnet steps
