Overview of the Issue

Using GitLab, if Atlantis is processing some projects in an MR and then another commit is pushed to that MR, GitLab pipeline status changes will fail with a 404 error.

Reproduction Steps

Environment details

Atlantis version: 0.30.0

Additional Context

This is because the current GitLabClient UpdateStatus function gets the current pipeline ID from the head of the MR branch rather than from the commit. This will return the incorrect ID for the first Atlantis run once the second commit has been pushed, and the relevant statuses won't yet exist on the new pipeline.

Relates to:

4950

This will return the incorrect ID for the first Atlantis run once the second commit has been pushed

We're also seeing that problem on repositories that don't have CI pipelines configured (i.e. there's no .gitlab-ci.yml).

In those cases, the first commit in the MR causes Atlantis to successfully create a new pipeline for that commit's sha. So far so good. But when a new commit is pushed (including if the current commit is rebased and force-pushed), Atlantis expects to find a new pipeline for that new commit sha - but no such pipeline exists! So the call to SetCommitStatus() gets made with the new sha and the old pipeline id - which GitLab rejects with an HTTP 4xx error due to the provided sha not matching the provided pipeline id.
