What does this MR do and why?

Exit early in setting up the test environment for non-VCS test components. openbao is such an example. This component uses the gitlab:secrets_management:openbao:download_or_clone Rake task that downloads the openbao binary without setting up the GIT repository in tmp/tests/openbao. When the test environment is being set up, the test helper calls component_timed_setup which invokes the GIT binary with the following arguments:

git -C tmp/tests/openbao merge-base --is-ancestor <COMMIT_SHA> HEAD

Due to the design of GIT, it traverses all directories until it finds the .git directory against which it can execute the command mentioned above. In our case, the GIT reaches the GitLab repository, which might be slow to respond.

It was reported by team members that this patch reduces the setup time from 2+ minutes to 2 seconds depending on the GIT repo status:

Before: Test environment set up in 160.159391346 seconds

After: Test environment set up in 2.480034855 seconds
