Added directive to `custom_php_ini` to add fpm pool directives
Hi, I needed to add directives for php fpm 'OPTIONS' tab -> inside existing php.ini settings textarea:
process.priority
pm.status_path
etc..and that are fpm pool directives but the issue is that plugin nginx_plugin.inc.php file wrappes it in php_admin_value[] so I ended up with solution to prefix line with 'POOL' keyword and escaped it
