### `ynh_add_fpm_config` is used to set up a PHP config.
### You can remove it if your app doesn't use PHP.
### `ynh_add_fpm_config` will use the files conf/php-fpm.conf and conf/php-fpm.ini
### If you're not using these lines:
###		- You can remove these files in conf/.
###		- Remove the section "BACKUP THE PHP-FPM CONFIGURATION" in the backup script
###		- Remove also the section "REMOVE PHP-FPM CONFIGURATION" in the remove script
###		- As well as the section "RESTORE THE PHP-FPM CONFIGURATION" in the restore script
###		With the reload at the end of the script.
###		- And the section "PHP-FPM CONFIGURATION" in the upgrade script
