Resolve "Gather heartbeats on samarbeid-collector"
Closes #1199 (closed)
Implements:
- automatic heartbeats only if environment variable is set (otherwise no crontab entry for this task is created)
- create nightly job to send HeartbeatStat to configured collector as hash (for data sent see test/cassettes/stats-heartbeat.yml for example)
