Repro steps:
1. start Package Manager dialog
2. go to online tab and install Microsoft.Aspnet.WebApi.Odat
3. go to update tab and click UpdateAll
4. check fiddler requests
Expected: Both NuGet-DependentPackage and NuGet-DependentPackageVersion header are shown
Actual: none was shown
Comments: I think for this case, it's okay that the headers are not sent. Each package is being updated, not just the dependent package, so the Update operation would happen regardless of the dependency on the package.
