CLOUDSTACK-2682: Sleep 1 second before switch to BACKUP
To prevent backup.sh preempt master.sh when keepalived switch to MASTER then
back to BACKUP immediately.
Since it would take at least 3 seconds for BACKUP to switch to MASTER(vrrp
timeout), the fix won't cause chaos when keepalive try to switch to MASTER.
> Redundant router: Router switch to MASTER then immediately switch back to
> BACKUP would failed to work

> The scripts master.sh and backup.sh are called at the same time when the
> "backup" RvR switch to MASTER then immediately back to BACKUP, because of the
> file lock mechanism we're using, there is a chance that backup.sh may be
> called
> before master.sh, then result in router seems in MASTER state(though
> keepalived
> still reports BACKUP state).
