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
- empty_lb_backends: event-elb

Changes since v3:
- rebase on top of 'add empty_lb controller_event for logical router pipeline'
- update documentation
- added a unit test for the meter option in the "action parsing"
Changes since v2:
- fold patch 'Repair memory leak for OVN controller events'
- fix memory leak of meter string
Changes since v1:
- fix subject

Lorenzo Bianconi (2):
  OVN: add meter support to trigger_event action
  OVN: northd: add rate limiting support for SB controller events
