Running async actions on captured synchronization context

[yevhen]

Runnng Polly inside MS Orleans grain is not possible, since Orleans uses custom TaskScheduler and due to automatically added ConfigureAwait(false) action escapes it and runs on different thread, thus breaking single-threaded guarantee provided by Orleans.

Is that possible to add an overload for RetryAsync\WaitRetryAsync that will allow to control that behavior?

P.S. I'll be happy to send a PR but I have no idea what feature/project type my VS15 installation is missing, that I cannot load Polly.Shared projects. It tell me that The imported project "C:\Program Files (x86)\MSBuild\Microsoft\WindowsXaml\v14.0\8.1\Microsoft.Windows.UI.Xaml.CSharp.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk. C:\Program Files (x86)\MSBuild\Microsoft\WindowsXaml\v14.0\Microsoft.Windows.UI.Xaml.CSharp.targets 😟

Is that ExpressionDesigner that need to be installed?

Great catch - I'd never had figure this out in our project :-) I wonder if missing project type might be Xamarin Shared ?

I've figured out that I don't have Windows Phone SDK installed. Done that.

@michael-wolfenden will you accept PR that fixes aforementioned problems? We can discuss api changes before I even try or I can proceed with PR, so there will be something eligible for further discussion?

Sketching that, I think it could be implemented without any breaking changes.
