tests/remote: Add monitor.py
Add monitor support. This supports monitors added to the current interfaces. This also support standalone monitor with multi interfaces support. This allows to get logs from different channels at the same time to one pcap file. Example of t3-monitor added to config.py file. Signed-off-by: Janusz Dziedzic <janusz.dziedzic@tieto.com>
