CLOUDSTACK-4199 Fixed redundant router fail over
When master router down, the back up router is entered into FAIL state
but it supposed to enter into master.
This issue is happening because the the enable_pubip.sh script triying to
ifdown and ifup the eth2 interface. Which is failed. So master.sh script got
failed. Fixed by doing ifdown force
> Redundant Virtual Router - no failover occur
