> ZKFC add HealthCallbacks by default, this can do quiteElection at least. but
> we often want to be alerted if there is fail over occurring(such as send
> email, short messages), especially for prod cluster.
> There is a configured fence script. maybe we can put all these logics in the
> script. but in reasonable, fence script does only one thing: fence :)
> So I added this patch, we can configure customized HM callback method, if
> there is no configuration, then only HealthCallbacks is added.
