Flower Default User + Ingress

[Muchembi]

1. I noticed that when securing Flower, the chart only offers the option for setting the password but no user. Is there a default user which takes on the password? Or is there a way to configure both the user and password?

2. It would be great if there was an option to enable the web and flower ingresses individually. i.e.
   ingress.web.enabled and ingress.flower.enabled as oppossed to the global ingress.enabled.

1. It looks like Airflow still does not support any authentication methods for flower other than basic auth:
   • https://airflow.apache.org/docs/apache-airflow/2.9.1/security/flower.html
   • https://airflow.apache.org/docs/apache-airflow-providers-celery/stable/configurations-ref.html#celery
   • Basic auth is just passing an Authorization header with base64 encoded username:password value, so its more like a "token" than a username/password.
   • I would be interested to know if you could setup one of the OAuth login types in Airflow's flower, but I am not sure you can set the require start args like --auth_provider
2. You can raise a PR if you like, we can discuss it:
   • I think most people never notice because they run with flower disabled (as its a bit of a security risk), so the flower ingress is not created. Or they use KubernetesExecutor and so celery is not used at all.
   • But we could add a per-ingress enabled value which overrides the overall enabled value.
