Description
As a user of NKG in a kubernetes cluster with lots of incoming traffic
I want to be able to horizontally scale NKG within my cluster
So that I can provide additional capacity for incoming traffic
And so that my Gateway can have higher availability.
Acceptance
- Users are able to set the number of replicas they would like to scale to for any gateway.
- A leader is elected amongst the replicas of NKG to write to the Kubernetes API.
- Incoming traffic is distributed evenly across replicas for that gateway.
