@Yoda-BZH Thanks for the contribution.

@arthurlogilab Can you confirm that this is how phpversion should be set in the pillar, after your PR (#167)?

@myii the contribution by @Yoda-BZH is to signify that the phpversion can also be specified for a given php-fpm pool. A quick look at the code makes me think this should work, I wouldn't be so sure with a list there. I don't think there's a need to though.
