WSA is sending out XFF headers to the destination server for HTTPS traffics

* Downstream proxy:
- Perform HTTPS decryption/inspection
- Set to send X-Forwarded-For header from GUI and CLI

* Upstream proxy:
- Configuration to do not inspect HTTPS traffics or Tunnel/passtrough
- Set to do not send XFF header from GUI and CLI
- Set to Use Received Headers from the downstream proxy

the enhancement request is to not send the XFF header out to the destination server using their current scenario means that they require the upstream proxy WSA to not applying XFF headers for HTTPS traffics that have been decrypted before and has been set to send XFF header to the upstream WSA
