GitHub provider on Start Page should use the new Clone API

[prasethu]

In VS 2017, we've introduced a new Clone API that enables cloning in Team Explorer and returns progress through an IProgress.

To enable the Start Page to display progress in the status bar, the GitHub provider should pass on the IProgress to the Clone API.

A sample usage of the new Clone API can be found here:

Specifically this file: CloneAPISample/VSIXProject2/Command1.cs

@prasethu Thanks for the heads up, we'll get this included on our roadmap!

@prasethu - I've implemented that here:

49a16ae#diff-37b2ed98a57be40299d610a06bbc51b8R68

This seems to work, however I'm not sure if we should be creating a new Progress<ServiceProgressData> there (as in your sample) or if the intention was that we should be passing on the IProgress<ServiceProgressData> that is passed to us in AcquireCodeContainerAsync?

@grokys Sorry about the late response but yes you should be passing it over to the clone api.
