[php] Set required PHP 7.1 in code comments and readme (#6188)

* Bump PHP version to 7.1 in readme

* Bump PHP version to 7.1 in class templates

* Remove HHVM from Travis CI config

PHPUnit dropped support of hhvm, so build unlikely will pass tests.
sebastianbergmann/phpunit#3320 (comment)

* Remove sudo: false from Travis-CI config

Official doc recommendation:
https://docs.travis-ci.com/user/reference/trusty/#container-based-infrastructure

* Change tested versions to 7.1, 7.2 in Travis-CI

* Remove PHP_CodeSniffer from dev dependencies

There is another linter(PHP CS Fixer) which is fully configured while
CodeSniffer isn't configured at all.

* Use caret instead of tilde in dependencies

^2.12 equals (>= 2.12.0 && <3.0.0) while ~2.12 is (>=2.12.0 && <2.13.0)

* Refresh samples
