Add a UserFactory for ASP.NET classic

[mrmonday]

Via #243 (comment)

This is currently supported in SharpRaven, and should be supported in sentry-dotnet to support migration to the new SDK.

This came up again, a user who's having problems customizing the user set on ASP.NET classic.

@mrmonday give ASP.NET classic is essentially no longer maintained, do you still this this feature should be added?

[mrmonday]

ASP.NET is supported as part of .NET Framework, which follows the Windows support lifecycle (see: https://docs.microsoft.com/en-us/lifecycle/faq/dotnet-framework).

Since .NET Framework is included in Windows Server 2022, this means it is supported and maintained until at least 2031 - see: https://docs.microsoft.com/en-us/lifecycle/products/windows-server-2022.

There are lots of legacy applications which use ASP.NET and cannot be easily ported to .NET 5+. For example, anything that uses ASP.NET Web Forms would essentially need a complete rewrite.

I think as long as .NET Framework is supported by Sentry, this feature continues to make sense.
