Summary

As a user of cluster logging, I want pod and namespace labels to be shipped with log entries as-is, so that it is easier to query by label

Acceptance Criteria

• Verify Pod and namespace label keys appear on a log entry the same as they are on a pod
• Verify Pod and label keys appear on a log entry flat_labels the same as they are on a pod

Notes

• De-doting was added in 3.x to account for an issue against Elasticsearch 2.x
• Replacing with underscores has made it less obvious how to query logs
• This would be a backward incompatible change for anyone trying to query using the old format
