[Integration] Include gitlab as another integration

[adrianriobo]

Previous fixed token on gitlab is deprecated

https://docs.gitlab.com/ci/runners/new_creation_workflow/

In this case we would need https://www.pulumi.com/registry/packages/gitlab/api-docs/runner/#gitlab-runner to be created and use the authentication token from outputs to use as param on the runner exec within the cloud init

We will need to use https://www.pulumi.com/registry/packages/gitlab/api-docs/userrunner/ to comply with new runner workflow

I'm following because our team talked about gitlab runners and the potental to spin up our own. I thought about how mapt has github runner integration and that we should push a feature in mapt to support gitlab runners. Then coincidentally I found this feature issue 😆
