Short report as widget on external sites

I want to suggest this new feature for geohealthcheck: provide a method that exposes a javascript snippet or dynamic image representing the current/recent state of a service to be represented as a logo on an external website (like a catalog) having a reference to a wms/wfs service monitored by geohealthcheck.

We need a mechanism to identify a certain monitoring by url#layername (instead of using resource-id, which is not known in the external website.

The external website would include a snippet like:

```html



```

Geohealthcheck will return an image presenting the current (or last month) service quality (or 404 if the service is not monitored).


An additional feature could be that in case the service is not monitored yet, a monitor could be automatically set up (is that risky?)
