Add Support for HttpContext.RewritePath of 2 params and 4 params

[Clounea]

Summary

The HttpContext in adapter only supports RewritePath(String). But there is also usage of RewritePath(String, Boolean) and RewritePath(String, String, String, Boolean).

Motivation and goals

RewritePath(String, Boolean) and RewritePath(String, String, String, Boolean) are used in SharePoint Online. But they are not supported in the adapter. I use the code below instead.

// case1: 2 params 
// old one 
context.RewritePath( newFilePath + originalPathInfo, true);
 // my workaround
context.RewritePath(newFilePath + originalPathInfo)

// case2: 4 params 
// old one 
context.RewritePath( newFilePath, originalPathInfo, originalQueryString, true); 
// my workaround
context.RewritePath(newFilePath + originalPathInfo + "?" + originalQueryString)

I wonder if there is plan to support the API.

In scope

Add support of RewritePath(String, Boolean) and RewritePath(String, String, String, Boolean)

Examples

context.RewritePath( newFilePath + originalPathInfo, true);

context.RewritePath( newFilePath, originalPathInfo, originalQueryString, true);

Happy to take a PR for this. Here's what ASP.NET Framework is doing here: https://referencesource.microsoft.com/#System.Web/HttpContext.cs,e1239e4275e728f9. That's more to understand the importance of the parameters - the code won't be a drop in replacement :)
