Some Issues about Running locally

[ShawnZ777]

• There's an issue that the document told me to use $ docker build -t atf_headless_browser . to build an image.
  However, in start.py, it sets the image name with IMAGE_NAME = 'atf_headless_runner'.
  So when I run the start.py, it can not create a container until I rename the image to make sure they are the same.

• And the second issue is an Error during login. It can not find the file with sn_passwrod.
  There will be a "FileNotFoundError: [Errno 2] No such file or directory: '/var/servicenow/C:\\\\ProgramData\\\\docker\\\\secrets\\\\sn_password'"
