cloudflared: refine config.yml

cloudflared: refine config.yml

The config.yml is an example of a tunnel local configuration.
But the cloudlfared treat it as a real config and fails to start.
So to avoid problems let's comment all the statements.

The `url: http://localhost:8000` is not a valid config option.

Additionally add a smale of configuring ingres rules.

The cloudflared.config has missing option token.
