Integrate PHP to use server version on Ubuntu

[seventhstar]

I see that there is a new release of VestaCP (#17). The VestaCP site talks about PHP7 working with this version. I've updated my VestaCP however still find that it is using PHP5.4.45.
I noticed that on sites: http://forum.vestacp.com/viewtopic.php? ... hp7#p53019
That it talks about changing: user/local/vesta/conf/vesta.conf and replace the variable by WEB_BACKEND='php7.0-fpm'
However I can't find the term: WEB_BACKEND.
