apps_vhost_plugin.inc.php refers to hard coded php version causing 502 errors

symptom (not the root cause)

http://server:8081/phpmyadmin and http://server:8081/webmail fails with Invalid Gateway error from NGINX

caused by

/etc/nginx/sites-available/apps.vhost is using tcp (fastcgi_pass 127.0.0.1:9000;) for locations phpmyadmin and squirrelmail. This causes the 502 error.

temporary fix

changing both locations to use socket (fastcgi_pass unix:/var/lib/php7.1-fpm/apps.sock;) resolves the issue.

However, /etc/nginx/sites-available/apps.vhost is overwritten by /usr/local/ispconfig/server/plugins-available/apps_vhost_plugin.inc.php using the template /usr/local/ispconfig/server/conf/nginx_apps.vhost.master after a reboot. Thus, the issue surfaces again afterwards.

problem (root cause)

apps_vhost_plugin.inc.php refers to hard coded php version in line 172:
if(file_exists('/var/run/php5-fpm.sock') || file_exists('/var/run/php/php7.0-fpm.sock')

Since used version of php is 7.1, produced apps.vhost contains the tcp version of the statement:
fastcgi_pass 127.0.0.1:9000;

correct behaviour

Testing for /var/run/php/php7.1-fpm.sock would have produced the socket version
fastcgi_pass unix:/var/lib/php7.1-fpm/apps.sock;

solution

apps_vhost_plugin.inc.php line 172 if condition must be modified to seek for the file with a dynamic php version (I do not know how)

environment
