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.

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?

Replace namespace-specific application.js files with namespace-bundle.js files.

Following up on the per-page JavaScript improvements, I wanted to replace the use of `application.js` with `namespace-bundle.js` to prevent confusion when downloading more than one application.js file.

This is pretty much just for the sake of clarity.

Limit git rev-list output count to one in forced push check

## What does this MR do?
It adds `--max-count=1` to the git command used to check for forced push, this way we can have a brief yet indicative output, saving some time used to split the string returned.

Don't think so.

It could allow for faster check of forced pushes.
