WIP: Inherit from CodeClimate image directly

To avoid the downloading of the underlying codeclimate image, we can create a docker image from the original image directly. While this is working, the job definition for codequality must be updated to work with this new version.

Note: This is an experiment, to show it's possible to avoid the downloading each time. Nevertheless, the job definition must be updated, so we will wait for the include feature before going further with this MR (hence the WIP: -> Do not merge!).
