What this PR does / why we need it:
Implements OTLP/Traces (OpenTelemetry) output.

Folding Falco events into traces allows them to be represented as "hierarchical" views.
Using a TraceID taken from container.id (or Kubernetes labels down to k8s.pod.name if present), all Falco events will be "rooted" under the container where it occurred, enabling a tree~ish view of these.

Which issue(s) this PR fixes:

Special notes for your reviewer:
Will provide some screenshots of these hierarchical views, as shown by an OTLP Traces backend like Jaeger or Grafana Tempo.
