Update PHP CLI docker image and integrate with Warden prebuilt environments

[hardyjohnson]

Update the provided pre-built Warden environments to use the dedicated PHP CLI image / docker service for PHP CLI tooling. This service would become the default target for the warden shell command. Below I have tried to provide an outline for an upgrade path / requirements for this feature based on discussions I have seen here.

Requirements

• Use a small image (decide on image upgrade path from centos base images).
• CLI image in line with PHP image and version for applications, but not directly tied to php-fpm image and service configuration.
• Configure tools desired for an application / environment
• Application path mappings
• Target CLI service as the host for warden shell
• Reconfigure the php-fpm hosts to remove any dependencies and tools
• Shell (bash)
• New base image: php.net:VERSION-cli-alpine?
