fix(argocd): disable ServerSideApply for OpenStack Helm Apps

OpenStack Helm Kubernetes Jobs need force=true to have them be replaced
since they need to stick around. We've battled with ArgoCD here a bit
and the current issue is argoproj/argo-cd#23226. Since upgrading from
ArgoCD 3.0.11 to 3.1.x they've made force=true and ServerSideApply=true
incompatible so disable ServerSideApply.
