+ Customer wants to enable  Stream (stdout/stderr) information in logs collected by Vector.

+ Customer is trying to setup log forwarder to forward logs to an external Logstash instance and are currently using the 'fluentd forward' protocol to forward the logs to Logstash.

+ By looking at the logs received at logstash cu Noticed that the entries don't contain any information from which log stream (stdout or stderr) the logs have been received.

+ Because this information is dropped in the fluentd configuration (https://github.com/openshift/cluster-logging-operator/blob/791ca54e5598a004d03c82722262f4e44873597c/internal/generator/fluentd/ingress.go#L298).

+ As Customer is planning to migrate from Fluentd to vector as collector , so  want to enable  Stream (stdout/stderr) information in Vector.
