test: add test to verify queue credentials are locked down

[YutongLi291]

What was the problem/requirement? (What/Why)

Queue credentials on the worker should only be able to be able to be accessed by the queue user.

We should verify this to prevent security concerns and regressions in the future.

What was the solution? (How)

Add a test that verifies this behaviour that other users on the worker instance cannot access the queue credentials.

Also verify that a different queue also cannot access another queue's credentials.

What is the impact of this change?

Better verification that other users cannot access queue credentials.
