Ingest and Process Apache Common Logs for Elasticsearch

Ingests Apache HTTP Server access logs (Common Log Format) and optimizes them for Elasticsearch. Parses CLF fields, filters health check and static asset requests, maps HTTP status codes to OTLP severity levels, masks sensitive data, removes high-cardinality fields, adds Elastic Common Schema fields, samples successful responses, deduplicates error bursts, and batches the results for delivery to Elasticsearch.
