Test case for iperf example.
This test case might have problem running on windows:
1. direct use of `make`
2. use `sudo killall iperf` to force kill iperf, didn't implement windows version
The test env Example_ShieldBox do need the following config::
Example_ShieldBox:
ap_list:
- ssid: "ssid"
password: "password"
outlet: 1
apc_ip: "192.168.1.88"
attenuator_port: "/dev/ttyUSB0"
iperf: "/dev/ttyUSB1"
apc_ip: "192.168.1.88"
