Function example_configure_stdin_stdout() was used for simple UART I/O operation in CI to enter test env configuration (wifi ssid, IPs, etc). It could be called multiple times, but didn't handle the situation where we install UART interrupt from multiple source (e.g. in ICMP tests, where we first need to enter wifi credentials of test AP and then we start ping-cmd console to handle ping commands)
