[Do not merge] CI Test

[benaadams]

This is #635 with updated feeds

3 out of 4 runs fails with Exit Code 139 on linux https://github.com/dotnet/coreclr/issues/3101
Generates warning NU1006: Dependencies in project.json were modified

Otherwise its green and no hangs, even enabled the disabled mono tests! (though should use #635)
