Add client SSL validation to nginx only when there are CA certificates
With nginx, we need to automatically save changes or remote will not work at all
nginx should be disabled always or it will interfere with webserver on port 80 on 3.0 -> 3.1 upgrades
Use the CA_CERT_FILE constant always so the file name will always match
