Fine-tune CORS headers for non pre-flight requests [APIM 4.1.0]

[Sumudu-Sahan]

Current Limitation

Currently, the CORS headers are included in all the requests, even if that is a non-pre-flight request.

Suggested Improvement

Need to fine-tune the CORS headers list and send appropriate list of CORS headers in the response of non pre-flight requests.
