Entrypoint override in `.gitlab-ci.yml` weakens security abilities
## Summary
The newly introduced extended Docker configuration in `.gitlab-ci.yml` !596 breaks our ability to secure privileged jobs such as docker build.
This use case is outlined in detail in the runner documentation here: https://gitlab.com/gitlab-org/gitlab-runner/blob/master/docs/executors/docker.md#the-entrypoint
Can you restore the ability to restrict what commands are run in a specific job? (be it with entrypoint or another mean)
