 The network status and descriptors are obtained every 5min
 https://gitweb.torproject.org/sbws.git/tree/sbws/lib/relaylist.py#n144.
 Is there any reason for that?.
 I think torflow obtain them as they come.
 It could be done with steam using:
 {{{
 controller.add_event_listener(
             listener_fn, EventType.NS, EventType.NEWDESC)
 }}}
 Also, instead overwriting those values, Relay could have a dictionary (key
 would be the timestamp) with a subset of the attributes of document, in
 case we might need to calculate median/mean of those attributes
