Fix for Flaky test for issue 433

[vibrantvarun]

Description

Currently we were using the "phase-results-pipeline" pipeline name at 4 places. This is creating the below issue

    {"error":{"root_cause":[{"type":"resource_not_found_exception","reason":"pipeline [phase-results-pipeline] is missing"}],"type":"resource_not_found_exception","reason":"pipeline [phase-results-pipeline] is missing"},"status":404}

The issue is coming when integ tests run in multithreaded environment.

Consider a scenario where test1 starts executing and it creates a pipeline with name "phase-results-pipeline" . At the same time test2 is about to end(Which also use the search pipeline with the same name) it is at the stage of cleaning up the resources. So when the test 1 tries to use the search pipeline it will not find the pipeline because test2 deleted it. This is the reason of flakiness.

The Fix is

I have used different names in all the impacted test classes
