Alberto Fernández Capel f0777f996c Space editing sessions heartbeats with an increasing backoff
We send the first heartbeat as soon as the session start.
The next ones are sent (if there's any activity)
when the editing session is about 30 and 60 seconds.
Then at 2min, 3min, 4min, 5min and later on every 5min.

The backoff is not reset, so if due to inactivity the
session expires in the server the backoff will still be
the same.
