WIP: Increase security mechanisms for specs that need the tunnel
What does this MR do?
In order to re-enable safely the QA Tunnel, we are ensuring new flows are in place before the specs run on the GitLab instance in the CI pipeline:
- disable signups
- change the root password to a secure tunnel password
Context: https://gitlab.com/gitlab-com/gl-security/security-operations/sirt/operations/-/issues/1060#note_426100103 (the first two points)
The creation of a parallel scenario for Tunnel (instead of Kubernetes) will help migrate and test iteratively the new approach
