[Docs] karaf.lock.delay in example is set to very low number.

The example in docs at http://karaf.apache.org/manual/latest-2.2.x/users-guide/failover.html assigns karaf.lock.delay=10. The karaf.lock.delay is passed to Thread.sleep() which takes a value in milliseconds. The default value for karaf.lock.delay is 1000.

Perhaps the intent was to set the value to "10000" rather than "10". The value of 10 create an excessive number of update queries .
