update index random function to fix the bogus document deletion

[neetikasinghal]

Description

This change updates the index random function to delete the bogus documents and add a refresh in the function such that the bogus documents are deleted and refresh ensures that the search doesnt account for the deleted segments.
This should fix some flaky issues encountered after adding the indexRadomForConcurrentSearch function to the tests.

Also, added TransportTwoNodesSearchIT.java to use indexRandomForConcurrentSearch.
