Anonymous auth breaks Kibana healthcheck

[laurivosandi]

I am using following for Kibana, it works as expected besides the healthcheck that seems to be polling /login. I suggest making the healthcheck endpoint configurable at least, I have it manually changed to /app/home for example

  config:
    xpack.security.authc.providers:
      anonymous.anonymous1:
        order: 0
        credentials:
          username: "elastic"
  secureSettings:
  - secretName: elasticsearch-es-elastic-user
    entries:
    - key: elastic
      path: xpack.security.authc.providers.anonymous.anonymous1.credentials.password
