Fixing client:rest-high-level tests for ppc64le.

[Sunidhi-Gaonkar1]

Describe the bug

Hi Team, I am working on validating Opensearch v2.11.1 on ppc64le, while running the testsuite the tests client:rest-high-level:integTest and client:rest-high-level:asyncIntegTest were failing due to the floating point difference between x86 and ppc64le. I had to make the following change fo get the tests passing.

@Sunidhi-Gaonkar1 Thanks for filing this issue. It would be useful if you had instructions for how to get a ppc64le environment for validating this scenario.

Hi @peternied , Apologies for the late reply. You can request for a ppc64le VM here: https://osuosl.org/services/powerdev/request_hosting/. Please let me know if you have further questions.
