Remove rollup/security_tests YAML tests

[lkts]

Removing this test for following reasons:

• It's flaky and uses a hack to sleep for 5s (hardcoded). There is no good way to fix this, the only fix is to convert this into a java test. We don't do this due to other points below.
• This test does not test anything specific to rollup. It creates an index and then checks that index data is not accessible if a user does not have access to this index. The fact that index in question contains rollup data is irrelevant (to the best of my knowledge), rollup performs a regular bulk request. I expect this case to be well covered already elsewhere.
• Rollup is deprecated and we don't want to invest in its support.

Closes #111631.
