Updating scripts python library dependencies

for F27 systems from lanforge-scripts run: pip3 install --user -r python.3.6.requirements.txt --upgrade
from lanforge-scripts run: pip3 install --user -r requirements.txt --upgrade

Scripts accessing Serial ports.

to access serial ports add user to dialout and tty groups to gain access to serial ports without needing root access.
Most scripts run in user space to use the installed python package and not affect the os python packages.

Getting Started

The first step is to make sure all dependencies are installed in your system.

Example of running a chamber view test

example from cv_examples/ferndale_ucentral.bash

./create_chamberview_dut.py : Replace arguments with your setup. Separate your ssid arguments with spaces and ensure the names are lowercase
- ./create_chamberview_dut.py --lfmgr ${MGR} --port ${MGR_PORT} --dut_name ${DUT}
  --ssid "ssid_idx=0 ssid=Default-SSID-2g security=WPA2 password=12345678 bssid=c4:41:1e:f5:3f:24"
  --ssid "ssid_idx=1 ssid=Default-SSID-5gl security=WPA2 password=12345678 bssid=c4:41:1e:f5:3f:25"
  --sw_version "ucentral-01" --hw_version ea8450 --serial_num 1001 --model_num 8450
./create_chamberview.py : change the lfmgr to your system, set the radio to a working radio on your LANforge system, same with the ethernet port. Create/update chamber view scenario and apply and build it. Easiest way to get these lines is to build it in the GUI and then copy/tweak what it shows in the 'Text Output' tab after saving and re-opening the scenario.
- ./create_chamberview.py --lfmgr ${MGR} --port ${MGR_PORT} --delete_scenario
  --create_scenario ucentral-scenario
  --raw_line "profile_link 1.1 STA-AC 50 'DUT: $DUT Radio-1' NA wiphy0,AUTO -1 NA"
  --raw_line "profile_link 1.1 STA-AC 50 'DUT: $DUT Radio-1' NA wiphy2,AUTO -1 NA"
  --raw_line "profile_link 1.1 STA-AC 50 'DUT: $DUT Radio-2' NA wiphy1,AUTO -1 NA"
  --raw_line "profile_link 1.1 STA-AC 46 'DUT: $DUT Radio-2' NA wiphy3,AUTO -1 NA"

  --raw_line "profile_link 1.1 STA-AC 1 'DUT: $DUT Radio-2' NA ALL-AX,AUTO -1 NA"
./lf_wifi_capacity_test.py : Run capacity test on the stations created by the chamber view scenario.
- ./lf_wifi_capacity_test.py --config_name Custom --pull_report --mgr ${MGR}
  --port ${MGR_PORT}
  --instance_name testing --upstream 1.1.$UPSTREAM --test_rig ${TESTBED} --graph_groups ${GROUP_FILE}
