Context

From running Loki Operator in RHOBS we have learned that the default set of stream labels for the OTLP protocol [1] that we originally decided is too extensive for most cases which results. This results in Loki producing a higher number of chunks with said chunks having an average utilization rate of 20%. This is not ideal as it make Loki less performant. With this issue our goal is to change this and review our default set of stream labels and make the necessary adjustments. See [2] for the solution that we adopted for RHOBS

Acceptance Criteria

• Define a new set of stream labels
• The new set of stream labels should not break previous functionality
• The new set of stream labels should result on an improvement in chunk utilization rate
