test: move test-cli-syntax to sequential

[Trott]

It is unreliable under load and the CI failures are getting a bit out of
hand. Let's move it to sequential.

Assuming green CI, I'd like to fast-track this. Collaborators, please 👍 here for fast-tracking.

Fwiw, I would prefer to mark this as a flaky test…? Moving to sequential is not a solution, and making the failures appear less often is also not a good thing imo…

I see what you're saying for sure. IMO it fails so frequently that marking it flaky will likely turn our CI more-or-less permanently yellow, which will make us start ignoring flaky tests completely. I'd rather have it less frequently show up as red so at least we take note when it fails. Regardless, the issue for this should definitely remain open until this is sorted out. (I included Refs: and not Fixes:, which you probably noticed.)

The AIX failure was still this test. 😱

[Trott]

AIX again. I'm alarmed that moving to sequential doesn't help AIX much it seems.

Maybe moving it to sequential and mark it as flaky? If it still shows up in AIX that much..

[Trott]

It's green this time. If it continues to fail more than it succeeds on AIX, we can mark it flaky.
