and then, no instance_id will be returned. This value starts at 0 for the
first iteration instance, and increases by 1 each time a recovery restart is
executed. After reaching MAX_INT, the instance_id will reset to 0.
The placement of this function is important because after it is called, the
process id will change.
After registration, event driven health checking is not running.
This call return CS_OK value if successful, otherwise and error is returned.
