Running integration tests with elasticsearch-nio fails in Intellij

[ywelsch]

I cannot run integration tests in IntelliJ that use elasticsearch-nio due to security manager permissions issue. As we randomize between elasticsearch-nio and mocksocket, there's a 50% chance that any integration test such as testAckedIndexing fails on my machine.

Hi @ywelsch, I should be able to fix this once some work Ryan is working on is merged (#27881).
