get rid of fiware-service-path in public instance

[jmcanterafonseca]

As we no longer want to promote the usage of FIWARE Service Path, let's get rid of it from the public instances (so the harvesters should not use the fiware-service-path)

Note: This does not mean that we should change harvesters. Just configure them for not using service-path

• weather-{forecast, observed, stations} - needs to be changed (they do not support empty service-path).
• airquality-{madrid-observed, madrid-stations}, bicycle_hire_station_barcelona, import_pois_tourspain.py - needs to be changed too, but refactored too, to be aligned with weather-* ones.
• airquality-barcelona not working at all, broken upstream.

so I think it's better to split this issue to 3 steps.

• change weather-* - (it's easy to do)
• fix available links in docs
• refactor others
• fix other links.

these services are no longer working however It is considered their reactivation.

airquality (Madrid) is recovered and resolved some open issues on it. Need to analyse the rest of issues

[albertoabellagarcia]

Harvesting services should be done in a specific repo. This is not longer active
