Description

The script common_docker.sh in function start_file_server tests existence of python3, but executes command using python:

    command -v python3 >/dev/null 2>&1
    if [[ $? -eq 0 ]]; then
      python ${TEST_INFRA_DIR}/python3_fileserver.py &
      return
    fi

The script python3_fileserver.py uses python2 SocketServer which does not exist in python3. It should use socketserver.
