[ovs-dev] [PATCH 0/2] OVN: add rate limiting support for controller_events

Introduce the capability to associate a meter to each controller event
type in order to not overload the pinctrl thread under heavy load.
For each event type we need to define a naming convention for the related
meter:
- empty_lb_backends: event-elb
