weather: forecast up to 10 days

This service needs api key. For now I put it straightly into the url
It will need to be replaced, like in perl with {{ENV_APIKEY}} , but not sure if python supports this. Gonna look at it deeply.

This is nice to note, however, it might be confusing to see that there is no `/country` being added below this line. I believe the comment could go on and say that we're about to use `Geocoder` to actually use latitude and longitude of a location to get a precise weather forecast.
