Labels that all logs should have. Contain relevant metadata.
Set by the forwarder:
- log_cluster: id of the cluster where the log is produced
- log_hostname: id of the machine where the log is produced
- log_machinerole: role of the machine where the log is produced
- log_source: kind or type of log (kube, systemd, audit...)
Legacy labels:
- origin: should be the same as log_cluster, but this one is inferred by the aggregator instead of set by the forwarder
