s3: Avoid races to change the machine password in winbind
The machine password handler has code to deal with every node in the cluster
trying to change the machine password at the same time. However, it is not very
nice to the DC if everyone tries this simultaneously. This adds a random 0-255
second offset to our timed event. When this fires a bit later than strictly
calculated, someone else might have stepped in and have already changed it. The
timed event handler will handle this gracefully, it won't even try to do it
again.
