Fix memory leak of the callChoreo access token request helper function

[sadilchamishka]

Purpose

There is possible memory leak due to not closing the http connection after the required response is received.

In httpClient version 5.x the automatic resource deallocation happens but in httpClient version 4.x the deallocation has to be done.
ex: EntityUtils.consume(entityOne);
Ref:- https://www.baeldung.com/apache-httpclient-vs-closeablehttpclient#1-automatic-resource-deallocation-httpclient-4x

httpClient.execute(httpGetOne, responseOne -> {
          HttpEntity entityOne = responseOne.getEntity();
          EntityUtils.consume(entityOne);
          assertThat(responseOne.getCode()).isEqualTo(HttpStatus.SC_OK);
          return responseOne;
      });
