title: How to remove the default clickhouse user through users.d
body: <p>For a clickhouse production server, I would like to secure the access through a defined user, and remove the default user.</p>
  
  <p>I'm using a users.d/myuser.xml file to add a new user, and I would like to remove the default user by this means too.</p>
  
  <p>I can't find the right combination. It look like I should use the "remove" attribute, but it's not documented.</p>
