    Suggest using $http_host instead of $host (#14814)
    
    If the reverse proxy is not running in port 80, using $host won't forward the port in the HTTP request to airflow and it won't build the correct redirect URL.
    
    E.g.
    I have nginx and airflow running in docker in the default ports. My mapping for nginx x is 7003:80.
    The request http://myserver:7003/myorg/airflow/ will redirect to http://myserver/myorg/airflow/admin/ instead of http://myserver:7003/myorg/airflow/admin/.
