Fixed certificate.yaml manifest for perfdash
Fixed certificate.yaml manifest for perfdash

- Added missing annotation to issue temporary
  certificate. We didn't face the issue with it before
  because we were reusing already existing certificates.
- Removed perf-dash-canary.kubernetes.io dns name
  from certificate because we didn't put this subdomain
  in k/k8s.io/dns/zones-config manifests and it's actually
  unnecessary
