usage: $0 (start|stop|status|reload|monitor|validate-all|meta-data)
$0 manages the Platform's System Certificate Monitor (cert-mon) process as an HA resource
The 'start' ..... operation starts the cert-mon service in the active state.
The 'stop' ...... operation stops the cert-mon service.
The 'reload' .... operation stops and then starts the cert-mon service.
The 'status' .... operation checks the status of the cert-mon service.
The 'monitor' .... operation indicates the in-service status of the cert-mon service.
The 'validate-all' operation reports whether the parameters are valid.
The 'meta-data' .. operation reports the cert-mon's meta-data information.
