Ryan Parrish 54902f91e7 Update sensor.cert_expiry.markdown (#2701 )

`name` is an optional variable for `cert_expiry`. If you don't use it all your certs just show up as "SSL Certificate Expiry" as their name.

The cert_expiry sensor fetches information from a configured URL and displays the certificate expiry in days.

To add the Certificate Expiry sensor to your installation, add these options to configuration.yaml file:

# Example configuration.yaml entry
sensor:
  - platform: cert_expiry
    host: home-assistant.io

Configuration variables:

host (Required): The host FQDN (or IP) to retrieve certificate from.
port (Optional): The port number where the server is running. Defaults to 443.
name (Optional): The friendly name for the certificate.

Make sure that the URL exactly matches your endpoint or resource.
