CSharpClientGenerator : add config flag to use ConfigureAwait(false) optionally

[dpradell-dev]

Hi @RicoSuter,

First of all, thanks for your amazing work with NSwag. I'm using the CSharpClientGenerator to autogenerate a Unity SDK and so far it's working great in most platforms :)

The only issue I have is that my implementation doesn't require ConfigureAwait(false) as it's using UniTask. Would it be possible to add a config flag so we can set it to false if we don't want to include ConfigureAwait(false) at the end of every request?

Thanks again,

David

ConfigureAwait(false) caused an issue for me due to it losing the HttpContext when using the sync version of a method in some .NET Framework code. I was able to work around the issue, but being able to not include that would be helpful. In many cases, I believe it isn't even recommended anymore.
