Deprecated GitLab CI/CD variables

Read through this document to learn what predefined variables were deprecated and their new references.

GitLab 9.0 renamed variables

To follow conventions of naming across GitLab, and to further move away from the build term and toward job, some CI/CD environment variables were renamed for GitLab 9.0 release.

NOTE: Note: Starting with GitLab 9.0, we have deprecated the $CI_BUILD_* variables. You are strongly advised to use the new variables as we will remove the old ones in future GitLab releases.
