Adjust Monitoring expression
Adjust Monitoring expression

**Problem:**
- Cannot see `host` and `path` in `Ingress Upstream Response Time`
- Cannot see `Number of failed proposals`

**Solution:**
- Replace `nginx_ingress_controller_ingress_upstream_latency_seconds` by `nginx_ingress_controller_response_duration_seconds_bucket`
- Replace `count(up{job="exporter-kube-etcd-cluster-monitoring"}) by (instance)` by `sum(etcd_server_proposals_failed_total)`
