core: retry fencing operation in case of failure

retry fencing operation in case of a temporary failure

Up to now, if 'unknown' was returned while waiting for a certain status
('on' / 'off') , the while loop was exited with a proper message,
breaking the reboot sequence.
It seems that there are some cases in which a fencing operation may fail
temporarily and succeeded after a while.
This patch retries to get to the desired status 3 times before giving up
with the configured delay between each status check.
