Use CODECLIMATE_PREFIX when pulling / using code climate full image
What does this MR do?
Code Climate supports CODECLIMATE_PREFIX and it is passed to code climate containers but run.sh pulls code climate image with env variable CODECLIMATE_FULL_IMAGE which does not contain private registry prefix. This leads to CODECLIMATE_FULL_IMAGE to be pulled from Docker Hub. After this MR CODECLIMATE_FULL_IMAGE contains CODECLIMATE_PREFIX and private registry is used to get code climate image if CODECLIMATE_PREFIX is defined.
