Support for custom builds for all Php 7 versions

SHORT DESCRIPTION (required)

Currently we only have a dedicated folder to build for Php 7.1 in php and dev-cli services of docker compose file. We need to support dedicated builds for all Php 7 versions.

NEW USER HISTORY (required)

Docker compose services php, cron-jobs and dev-cli need to be able to make custom builds for all Php 7 versions.

CURRENT BEHAVIOUR (required)

• Docker compose services php and dev-cli only allow custom build for Php 7.1.
• Docker composer service cron-jobs uses a build context that is Php version agnostic but still a limitation to support custom builds for multiple Php versions, once they need to share the same build context, that will cause conflicts when installing dependencies.

EXPECTED BEHAVIOUR (required)

Be able to create custom builds for any Php 7 version in docker compose services:

• php
• cron-jobs
• dev-cli
