write logfile just before rebooting the host

Browse Source 
As discussed with @wido @pyr and @nuxro added an extra log line.

Tested it and it logs fine (tested to local disk) when syncing first:
Apr  3 15:31:23 mcctest2 heartbeat: kvmheartbeat.sh system because it was unable to write the heartbeat to the storage

By the way, it did also log to the agent.log but this extra log has the benefit of ending up in the system log so you'll probably find it easier there. Existing logs:

2015-04-03 15:31:23,950 WARN  [kvm.resource.KVMHAMonitor] (Thread-24:null) write heartbeat failed: timeout; reboot the host

This closes #145
