feat(logs): add standalone external collector for devices

[timojohlo]

Details

Introduces a standalone OpenTelemetry external collector (StatefulSet) that is independent from the existing logs DaemonSet collector. This new collector handles log ingestion from external devices — syslog (TCP/UDP/TLS) and traces (OTLP gRPC/HTTP) — and will later support routing to different kafka topics (audit, operational) based on defined attributes.

Pull request overview

This PR introduces a standalone “external” OpenTelemetry Collector (StatefulSet) intended for ingesting device/external inputs (alertmanager webhooks, deployment TCP logs, syslog, and OTLP traces) separately from the existing node-level logs collector (DaemonSet).

Changes:

• Added a new externalCollector values block and an external-collector.yaml template to deploy a standalone OpenTelemetryCollector when any external ingestion feature is enabled.
• Moved external-ingestion-related configuration (external events, syslog, syslog TLS cert, traces) off logsCollector and updated templates/docs accordingly.
• Bumped plugin/chart versions and updated CI test values for the new configuration structure.
