vmalertmanager: tracing configuration is ignored if VMAlertmanagerConfig is not used

[zekker6]

Currently, setting .spec.tracingConfig for VMAlertmanager which uses configRawYaml for the configuraiton will lead to silently skipping tracing config.
Seems like early return here -

operator/internal/controller/operator/factory/vmalertmanager/config.go

Lines 21 to 23 in 178ca2d

	if len(pos.configs.All()) == 0 {
	return baseCfg, nil
	}

Leads to skipping tracing configuration being applied here -

operator/internal/controller/operator/factory/vmalertmanager/config.go

Lines 110 to 116 in 178ca2d

	if cr.Spec.TracingConfig != nil {
	tracingCfg, err := buildTracingConfig(cr, ac)
	if err != nil {
	return nil, err
	}
	baseYAMLCfg.TracingConfig = tracingCfg
	}
