Proposed API

I propose to expose a public safe handle type with methods to set and query custom options. These methods would be a direct wrappers around WinHttpSetOption and WinHttpQueryOption, similarly to the concept of Socket.SetRawSocketOption.

public class SafeWinHttpHandle : Microsoft.Win32.SafeHandles.SafeHandleZeroOrMinusOneIsInvalid
{
    public uint GetWinHttpOption(uint option); 
 public void SetWinHttpOption(uint option, uint optionData);

go to runtime/src/libraries/System.Net.Http/tests/StressTests/HttpStress
run
1.	Linux: ./run-docker-compose.sh -b -clientstressargs "-maxExecutionTime 720"
2.	Windows: .\run-docker-compose.ps1 -b -w -clientstressargs "-maxExecutionTime 720"

run again for HTTP/1.1
1.	Linux: ./run-docker-compose.sh -b -clientstressargs "-maxExecutionTime 720 -http 1.1"
2.	Windows: .\run-docker-compose.ps1 -b -w -clientstressargs "-maxExecutionTime 720 -http 1.1"
