[Observability 5/10] Add OTEL config to Kubernetes manifests

[concaf]

Context

Add the environment variables needed for OTEL metrics export to the MCP server Kubernetes deployment manifests.

Scope

config/mcp/configmap.yaml

Add entries:

ENABLE_OTEL: "true"
OTEL_EXPORTER_OTLP_ENDPOINT: "http://otel-collector:4311"

Note: The OTEL Collector in the cluster uses port 4311 (not the standard 4317), per platform-config/config/otel-collector/deployments/base/021-otel-collector-deployment.yaml.

No deployment.yaml changes needed

The deployment already uses envFrom: configMapRef, so any key added to the ConfigMap is automatically injected.

Verification

• make generate-mcp-manifests produces valid output
• kubectl apply --dry-run=client -f mcp-server-manifest.yaml succeeds

Depends on

• [Observability 1/10] Add OTEL metrics foundation — telemetry package + main.go wiring #308 (telemetry foundation) — the env vars reference code from that issue

Note

The OTEL_EXPORTER_OTLP_ENDPOINT value may need to be adjusted per namespace. The exact service name of the OTEL Collector should be confirmed from the cluster.
