Eventscripts: change failure counts and behaviour for statd and nfsd.

We reduce the number of failures before attempting a restart.
However, after 6 failures we mark the cluster unhealthy and no longer
try to restart.  If the previous 2 attempts didn't work then there
isn't any use in bogging the system down with an attempted restart on
every monitor event.
