What does this PR do? Why is it needed?

• Originally, this test was added to have the smallest possible e2e test case that has connectivity issues (it takes only 1.5-2 mins to run, but enough to discover the issues with connectivity).
• However, now when we have connectivity issues resolved this test case is redundant, mainly because it doesn't do anything that is not done during our main e2e test case. So, while useful for debugging, having +2 mins to e2e run (w/o checking anything that is not already checked during our main test) seems to be a waste of resources.
