Function Compute to update SSL certificates from Let's Encrypt.

This function uses the Alibaba Cloud DNS service to authenticate the domain with Let's Encrypt. Your account must have access to this service, and you must use these enviroment variables to pass the credentials:

• AUTH_ACCESSKEY_ID
• AUTH_ACCESSKEY_SECRET

The function is intended to be run using a Time trigger. The domain must be passed in the Trigger Message.

• The config.py file is not provided, as you may already have your own configuration file/system (perhaps even using the enviroment variables of the FC). Just replace the config.config dictionary members with your own cofiguration parameters.
• A sample Dockerfile in provided, which you might adjust to your use case.
• A sample requirements.txt file is provided, which you might adjust to your use case.
• The FC checks the expiration time of the certificate, to verify if it must be processed.
• The --test-cert flag is passed to certbot. This is done mainly for testing, and should be removed for production.
