Refactor BYOO collector configuration for log chunking and resource overrides

[sbaum1994]

Summary

Refactor NVCA BYOO collector configuration so BYOO log chunking and BYOO telemetry resource overrides are first-class configurable settings. Operators should be able to tune these values through the NVCA operator configuration without patching generated workloads or relying on scattered implementation-only environment variables.

This Epic is informed by the config surface being added in #194 and should make that surface complete, documented, and safe for supported deployments.

Context from #194

PR #194 is adding more than basic log chunk and resource tuning. It introduces or updates:

• Structured agent.byooOtelCollector configuration in NVCA operator values.
• Helm values, schema, and README documentation in both NVCA operator chart locations.
• Agent config merge support for BYOO OTel collector settings.
• BYOO_OTEL_COLLECTOR_CONFIG_B64 as the structured BYOO collector config handoff, while preserving existing BYOO log chunking environment variables.
• Exporter helper timeout, retry, sending queue, and sending queue batch settings.
• OTel memory_limiter processor overrides.
• Metrics/traces batch processor overrides.
• A separate logs-only logBatch processor so log chunk behavior can be tuned independently from metrics and traces.
• Collector service telemetry log settings.
• Optional debug exporter fanout for generated pipelines.
• Config encode/decode, operator merge, and collector renderer tests.

Scope

• Define the supported NVCA configuration schema for BYOO log chunking, including max body bytes, dry run, exporter batch sizing, and logs-only batch settings.
• Define the supported NVCA configuration schema for BYOO telemetry resource overrides, including Kubernetes requests and limits for BYOO collector components and related telemetry containers where applicable.
• Preserve backward compatibility for the existing BYOO log chunking env vars while moving operators toward the structured config path.
• Plumb the supported settings through NVCA operator Helm values, schema, generated docs, agent config merge, and workload rendering.
• Validate that log-specific batch tuning does not unintentionally change metrics or traces pipelines.
• Add validation or guardrails for invalid values where practical, especially resource overrides and batch sizing.
• Add focused tests for config encoding, decoding, chart value merge behavior, collector rendering, and resource override propagation.
• Document supported defaults, examples, and upgrade behavior.

Acceptance criteria

• BYOO log chunking can be configured from NVCA operator configuration without code changes.
• BYOO telemetry resource requests and limits can be configured from NVCA operator configuration without manual workload patches.
• Existing deployments that rely on current defaults continue to work without configuration changes.
• Metrics/traces batching and logs-only batching can be tuned independently.
• Documentation and tests cover the supported public configuration surface.
