Merge branch 'ci-predefined-variables' into 'master'

Add predefined CI variables to GitLab

## What does this MR do?
This adds predefined CI variables to GitLab for container registry, pipelines, project name, etc. It also makes sure that all currently documented variables are send from GitLab. This is added to follow up on this proposal: https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/185#note_11844286. To migrate almost all variables out of Runner to GitLab to simplify adding a new of variables without the need for changing the GitLab Runner.

## Why was this MR needed?
Our CI variables miss a lot of crucial information that should be easily accessible. This tries to fill this gap.

## What are the relevant issue numbers?
Fixes https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/185, https://gitlab.com/gitlab-org/gitlab-ce/issues/18164, https://gitlab.com/gitlab-org/gitlab-ce/issues/18075.
