 """A bare-bones test server for testing cloud policy support.
 
 This implements a simple cloud policy test server that can be used to test
 chrome's device management service client. The policy information is read from
 the file named device_management in the server's data directory. It contains
 enforced and recommended policies for the device and user scope, and a list
