Title: Issue 1 sensing and caching

The sensor node perform the following tasks:

- sense data periodically and cache them into volume (20s)
- answer to HELLO REQUESTs with HELLO RESPONSE (in order to publish its existence)
- Aswer to DATA REQUEST with DATA RESPONSE (in order to download previousely saved data)

Leds show its status:

Led0: toggled when answeres to hello message
Led1: toggled when data is sensed and cached (every 15s)
Led2: toggled when data is sent to a requestor (when asked)
