tekton-pipelines-webhook specifies replicas and also has a HPA

[sellitforcache]

Expected Behavior

Reapplications of the tekton-pipelines-webhook Deployment do not cause scale back.

Actual Behavior

If scaled up with the HPA, reapplication of Deployment yaml will cause the replicaset to scale back to 1. This is temporary until the HPA scales it back up, but could cause disruption.

Steps to Reproduce the Problem

1. Set minreplicas on the HPA to 2
2. Reapply tekton-pipelines-webhook Deployment yaml
3. observe temporary scale back to 1 replica
