docs: def hosts_remove(hostsfile='/etc/hosts', entries=None):
      '''
      Remove a host from the /etc/hosts file. If doing so will leave a line
      containing only an IP address, then the line will be deleted. This function
      will leave comments and blank lines intact.
  
      CLI Examples:
  
      .. code-block:: bash
  
          salt '*' dnsutil.hosts_remove /etc/hosts ad1.yuk.co
          salt '*' dnsutil.hosts_remove /etc/hosts ad2.yuk.co,ad1.yuk.co
