Refactor configure index test

[rohanshah18]

Problem

After recent changes in integration test to use the existing index if it exists, the configure index test was required to be updated to consume less resources.

Solution

1. Refactored checkIfIndexExists code:
   a. To support both data and control plane integration tests
   b. Check if any index matches the criteria compared to old approach of checking the first index of the list and otherwise create a new index.
2. For configure test:
   a. Updated the beforeAll logic to check if an index exist
   b. Deleted the afterEach block to delete each index and save them for future test
