Release note: [1915448] Collector blocked pushing logs to internal storage because of global proxy settings

* If you did not set `.proxy` in the cluster installation configuration, and then configured a global proxy on the installed cluster, a bug prevented Fluentd from forwarding logs to Elasticsearch. To work around this issue, in the proxy/cluster configuration, set `no_proxy` to `.svc.cluster.local` so it skips internal traffic. The current release fixes the proxy configuration issue. Now, if you configure the global proxy after installing an OpenShift cluster, Fluentd forwards logs to Elasticsearch.
