Story (Required)

Horizontal scaling of the Tekton Results components (API and Watcher) is not easy because of two issues:

• gRPC uses HTTP2 and long lasting connections

• scaling Knative controllers require some extra changes - switching to StatefulSets from Deployments and properly managing number of buckets vs replicas. Some Tekton components already do that and the operator supports it, so we need to follow on that example.
