Bug 1045139

Description of problem:
In the event of a full host power outage (including fence devices) a "Failed to verify Host <hostname> Restart status, Please Restart Host <hostname> manually." alert is added to audit log after 18 failed fencing attempts.
The alert is not removed once the problem is resolved and the host is restarted.

Version-Release number of selected component (if applicable):
rhevm-3.2.3-0.43.el6ev.noarch

How reproducible:
Always.

Steps to Reproduce:
1.  Remove all power to an active host, including any fence agents that are configured.
2.  Wait 9 minutes for the reconnection timeout to elapse and the fencing attempts to begin.
3.  Keep waiting for 18 fencing attempts to happen.
5.  Observe "Failed to verify Host <hostname> Restart status, Please Restart Host <hostname> manually." alert added to audit log.
6.  Restore power to host.
7.  Restart host and "Confirm host has been rebooted".
8.  In webadmin portal edit host, go to "Power Management" tab, click test button to verify that fencing works. 

Actual results:
"Failed to verify Host <hostname> Restart status, Please Restart Host <hostname> manually." alert stays in audit log.

Expected results:
"Failed to verify Host <hostname> Restart status, Please Restart Host <hostname> manually." alert is removed from audit log.
