tasks: run `systemctl daemon-reload` after httpd.service.d updates
    
    Run `systemctl daemon-reload` after
    `/etc/systemd/system/httpd.service.d/ipa.conf` is created or deleted,
    otherwise systemd will not merge the file into httpd.service and therefore
    required environment variables will not be set for httpd.
    
    This fixes authentication failures ("No valid Negotiate header in server
    response") due to missing `GSS_USE_PROXY=yes` in httpd environment.
