$0 manages an OpenStack L3 Service (neutron-l3-agent) process as an HA resource

The 'start' operation starts the networking service.

The 'stop' operation stops the networking 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 networking service is running

The 'monitor' operation reports whether the networking service seems to be working
