- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary

change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/

extracted elasticsearch-logging service name as environment variable
**What this PR does / why we need it**:
Deploying the cluster-addon fluentd-elasticsearch with customized resource definitions can cause elasticsearch discovery to fail because the service name `elasticsearch-logging` is hard-coded in cluster/addons/fluentd-elasticsearch/es-image/elasticsearch_logging_discovery.go
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
-> none yet
**Special notes for your reviewer**:
The name of the environment variable is ELASTICSEARCH_SERVICE_NAME. When non is given the fallback service-name fallback is `elasticsearch-logging`
```release-note
[fluentd-elasticsearch addon] Elasticsearch service name can be overridden via env variable ELASTICSEARCH_SERVICE_NAME
```
