Rebase onto updated PR #320; remove ForceEnableTelemetry; fix test alignment
- Remove ForceEnableTelemetry from telemetry Config, driver_integration.go, and all call sites (connector.go) - Update feature flag tests to use new connector-service endpoint format ({"flags": [{"name": ..., "value": ...}]} instead of {"flags": {...}}) - Update exporter/integration tests to use new TelemetryRequest payload format - Update config/connector tests to reflect EnableTelemetry=true default - Fix rows_test.go NewRows calls to include telemetryCtx and telemetryUpdate args
