Add possibility to manage global settings of dedicated PHP handler per domain. At the moment adding custom settings in global section of the /var/www/vhosts/system/example.com/etc/php-fpm.conf gets overwritten during any change in PHP Settings of domain or on domain's repair.
Add funcionality to add such settings (emergencyrestartthreshold, emergencyrestartinterval, processcontroltimeout for example) to domain with dedicated PHP handler.
