        $0 manages an OpenStack NovaAPI (nova-api) process as an HA resource 

        The 'start' operation starts the nova-api service.
        The 'stop' operation stops the nova-api service.
        The 'validate-all' operation reports whether the parameters are valid
        The 'meta-data' operation reports this RA's meta-data information
        The 'status' operation reports whether the nova-api service is running
        The 'monitor' operation reports whether the nova-api service seems to be working
