PHP 7.2 support

[FEATURE] Initial PHP 7.2 images

    Add `docker/php-official/7.2` directory which is
    mostly a duplicate of `docker/php-official/7.1` and
    generated Dockerfile.

    Symlinked docker/php/7.2 to newly added on (see above).

    Add `docker/php-dev/7.2` directory which is
    mostly a duplicate of `docker/php-dev/7.1` and
    generated Dockerfile.

    Add `docker/php-apache/7.2` directory which is
    mostly a duplicate of `docker/php-apache/7.1` and
    generated Dockerfile.

    Add `docker/php-apache-dev/7.2` directory which is
    mostly a duplicate of `docker/php-apache-dev/7.1` and
    generated Dockerfile.

    Add `docker/php-nginx/7.2` directory which is
    mostly a duplicate of `docker/php-nginx/7.1` and
    generated Dockerfile.

    All „Dockerfile“ files in this commit are auto generated
    by running `./bin/console generate:dockerfile`.
