Description:

Adds a converter to generate SHA-512 digest. See the #34007 issue for more details.

Link to tracking Issue: #34007

Testing:

• Unit testing
• E2E
• Local testing
  • after applying changes, build opentelemetry-collector-contrib: cd opentelemetry-collector-contrib && make otelcontribcol
  • create config folder and place following config under otel-transform-sha512.yaml file:

    extensions:
      zpages:
        endpoint: 127.0.0.1:55679
    
    receivers:
      otlp:
        protocols:
          http:
            endpoint: 127.0.0.1:8080
    
    processors:
      batch:
      transform:
        log_statements:
          - context: log
            statements:
              - set(attributes["string.attribute"], SHA512(attributes["string.attribute"]))
    
    exporters:
      debug:
        verbosity: detailed
      elasticsearch:
        hosts: ["localhost:9200"]
        user: "elastic"

    service:
      telemetry:
        logs:
          level: debug
      pipelines:
        logs:
          receivers: [otlp]
          processors: [batch, transform]
          exporters: [elasticsearch, debug]
    
      extensions: [zpages]
