docs: Utility function to issue a command to all Turnstile instances.
  
      :param db: The database handle.
      :param channel: The control channel all Turnstile instances are
                      listening on.
      :param command: The command, as plain text.  Currently, only
                      'reload' and 'ping' are recognized.
  
      All remaining arguments are treated as arguments for the command;
      they will be stringified and sent along with the command to the
      control channel.  Note that ':' is an illegal character in
      arguments, but no warnings will be issued if it is used.
