sam_start - Start health checking

       The sam_start function is used to start health checking of application.  After calling this function, the
       active  process needs to send healthchecks within the registered time interval by calling sam_hc_send(3).
       If event driven healthchecking is configured by calling  sam_register(3),  an  internal  thread  will  be
       created and send health check confirmations four times per time_interval.

       Application must be registered by calling sam_register(3) before this function can be called.

       An application can always stop health checking by calling the sam_stop(3) function.

       If  SAM  is  initialized  with  quorum  policy  SAM_RECOVERY_POLICY_QUIT  or  SAM_RECOVERY_POLICY_RESTARTsam_start will block until corosync becomes quorate.
