claw-playbook should use PHP 7.1+

[whikloj]

Currently the claw-playbook ansible scripts load PHP 7.0. As we require PHP 7.1 or greater we should actually install PHP 7.1 or greater.

@kayakr nice, do you have any suggestions for the Centos side and do you feel like opening a PR with these changes?
