Startup issue with KIC wipes database about kubernetes-ingress-controller

[ichbinfrog]

This issue constantly occurs on our clusters making the Kong Ingress Controller not viable for production. Some further clarifications:

• It happens despite explicitly disabling the KongConsumer controller via environment variables

CONTROLLER_ENABLE_CONTROLLER_KONGCONSUMER: false

• Sometimes no log occurs and the Ingress Controller starts removing all tags from managed

updating service redacted  {
  "tags": [
  - "managed-by-ingress-controller"
  ]
}

deleting consumers redacted

I think this is due to the error handling done in:

kubernetes-ingress-controller/internal/dataplane/sendconfig/kong.go

Lines 64 to 69 in 9783552

	ok, err := cl.AdminAPIClient().Tags.Exists(ctx)
	if err != nil {
	return fmt.Errorf("Kong Admin API (%s) does not support tags: %w", cl.BaseRootURL(), err)
	}
	if !ok {
	return fmt.Errorf("Kong Admin API (%s) does not support tags", cl.BaseRootURL())

Shouldn't the default behavior be that tags are considered as enabled as long as this config is set?
